Researchers Discover 3D “Hidden” Quantum Matter States for Ultra-Quick Cryo-Memory

1T-TaS2 Interlayer Stacking and Electronic Properties An multinational team of researchers captured the first three-dimensional photos of a “hidden” metallic state within a crystal being turned on and off, advancing quantum materials research. A layered van der Waals material termed 1T-TaS2 is studied. This material could become the next generation of energy-efficient quantum computer “flash memory”.

“Hidden” Quantum Switch

Because of its complicated “charge-density wave” (CDW) states, in which electrons self-organize into “Star of David” patterns, 1T-TaS2 has fascinated physicists for years. This material is a Mott insulator at very low temperatures, inhibiting current flow by electron-electron repulsions. The material rapidly changes into a metastable metallic “hidden” state after a short electrical or optical pulse.

Scientists had trouble understanding what was happening inside the material's bulk during this shift until recently. The researchers used non-destructive, micro-beam X-ray diffraction and fluorescence to image the device in operando, or while it was actively switching. Most previous studies had only examined the surface.

Examine the Bulk Inside

At the Swiss Light Source, a 500-nanometer-thick 1T-TaS2 flake was tested with a micro-sized X-ray beam. The researchers used 100-microsecond electrical pulses to transform the material from equilibrium insulating to “fully-switched” metallic.

The 3D “tomograms” showed that switching reaches deep into the material, not only on the surface. Researchers found that the metallic hidden state grows after developing on the flake's edge, the shortest electrical current path, as current increases. The report says “the results reveal a long-range ordered switching region that extends well below the electrodes,” indicating that lattice strain and charge rearrangement created this new phase. This strain acts as a “quantum jamming” procedure to stabilize the concealed state after the electrical pulse stops.

Redefine Electronic Stacking

Additional theoretical support for these conclusions comes from parallel studies. Using Monte Carlo simulations, researchers found that the electrical properties of these van der Waals materials are directly influenced by the interlayer stacking, which is often random in mesoscopic flakes.

Hubbard repulsion causes insulating and metallic layers to coexist, according to dynamical mean-field theory. This complex “stacking physics” proves that 1T-TaS2's electrical activity is more sophisticated than band theory suggests.

Future of Quantum Computing

Technological implications are significant. Quantum processors require very low temperatures, therefore ordinary computer "flash memory" may not work. Due to its low-power switching between states at cryogenic temperatures, 1T-TaS2 may fulfill the “classical control electronics” needed for solid-state quantum information processing.

This breakthrough also opens the door to neuromorphic computing systems, which mimic the brain's neural architecture, using non-destructive 3D imaging. By understanding how strain and charge produce conducting “filaments” or regions, engineers can make more reliable and scalable memory chips.Scientists said, “Our combination of techniques demonstrates the potential of three-dimensional X-ray imaging to study bulk switching in microscopic detail.” This capacity should speed up the development of next-generation memory technology, which will be faster, smaller, and more energy efficient.

As the International Year of Quantum ends, the community celebrates a century of progress.

Quantum Mechanics 100th Anniversary

Scientists prepare for a quantum research milestone in 2026. UNESCO declared 2025 the International Year of Quantum Science & Technology to commemorate quantum mechanics' 100th anniversary. According to the ITU and IBM, quantum computing is now a worldwide ecosystem driven by workforce expansion and cooperation, not an annual lab experiment.

Century of Science, Decade of Access

IYQ recognition was given to 1925 discoveries that shaped nature. IBM reached a milestone as it approached the tenth anniversary of delivering the first quantum processor on the cloud. Over the past decade, open access has transformed physics into a global movement involving academics, technologists, and lawmakers from six continents.

More than 1,000 people in person and 2,500 online established quantum technology's future agenda at UNESCO in Paris in February 2025. As quantum technologies become real, industry experts underlined trust, openness, and responsibility.

A Long-Term Quantum Workforce

The IYQ focused on the need for a “quantum-ready” workforce. As governments create national quantum strategies, the focus has changed from involvement to coordinated actions. To fulfill these requests, IBM added advanced courses and improved Qiskit 2.x Developer Certification. These certificates establish a software competency baseline to help organizations and researchers define "quantum readiness."

Education activities extended outside traditional classrooms. The IBM and ITU Voices in Quantum event series examined how quantum research affects politics, business, and civil society with over 100 nations in attendance. Due to online tools like the Qiskit YouTube channel, technical explainers can simplify complex concepts for many pupils.

Breakthrough Participation and Action

Large public endeavors were the quantum community's most evident sign of momentum. Over 8,000 people from 115 countries registered for the 2025 Qiskit Global Summer School, a 30% increase over the previous year. Similarly, the Qiskit Fall Fest doubles its annual expansion by holding 150 activities for over 32,000 people.

These programs increasingly emphasize “Quantum in Action”—from theory to prototype. Over 400 participants from 30 countries used cloud-based quantum technology to solve real-world challenges at the ITU Future Leaders in Quantum (FLIQ) Hackathon. At the AI for Good Summit, the winning teams showed how artificial intelligence and quantum computing are working together to solve public-interest problems.

Assessing Success and Future

The increased need for openness has led to new benchmarking tools. The open-source Quantum Advantage Tracker was an important IYQ project. This combined effort allows researchers to evaluate quantum approaches against classical computing techniques in the “final stretch” toward quantum advantage, when quantum computers can solve problems beyond the most powerful classical supercomputers.

IBM and the Unitary Foundation also participated to a UNESCO-aligned ecological research. The research, which will be released in 2026, will outline the technology's global potential and problems based on a survey of 600 academic, corporate, and government institutions.

Researchers Improve Quantum Physics by Reaching Beyond-Breakeven Fidelity for Entangled Logical Qubits

Researchers from USC and other schools have reduced quantum processor flaws, advancing fault-tolerant quantum computing. Protected logical qubits outperform unprotected physical qubits in the same environment by combining QEC with Logical Dynamical Decoupling for “beyond-breakeven” performance.

In its early 2026 Nature Communications publication, the study addresses the fragility of quantum information, one of quantum physics' biggest concerns. Qubits, the foundation of quantum computers, are notoriously noisy and can wreck complex calculations.

The Limits of Standard Correction

Quantum Error Correction (QEC) codes solve the scientific community's problem, however they have a downside. Standard codes detect and rectify “physical errors” that affect qubits, but they often miss logical flaws that occur within the protected “code space”. The researchers noted in their article that such codes cannot detect logical errors. Arian Vezvaee and Daniel A. Lidar led the team to propose a hybrid technique to close this gap. At the logical level, they used Dynamical Decoupling (DD), which “averages out” noise using fast pulses.

LDD/NDD Hybrid Solution

The key innovation is using QEC code logical operators or normalizers as decoupling pulses. Normalizer Dynamical Decoupling (NDD) or Logical Dynamical Decoupling (LDD) suppresses logical flaws that the code would ignore.

This method was tested on IBM's transmon-based quantum computers, including the 127-qubit ibm_kyiv and ibm_marrakesh systems. They employed the [] code to turn two logical qubits into four physical ones. This code is ideal for testing because postselection discards faulty data to find problems.

Past Breakeven

The hybrid method was a hit. Logical Dynamical Decoupling and postselection considerably improved the faithfulness of entangled logical Bell states.

Their average postselected encoding fidelity was 98.05%. In a 55-microsecond test, shielded logical qubits maintained 92.89% fidelity, but unprotected qubits degraded far faster.

The experiment reached “beyond-breakeven” status. Quantum computing's “breakeven” point is when the system's best physical and logical qubits perform equally. The team went above and beyond to show that its QEC-LDD approach's net benefit exceeds the "overhead" or complexity needed to implement the protection.

Competing with “Crosstalk”

ZZ crosstalk was a major experiment challenge. Qubits' "always-on" contact with neighbors in superconducting transistor computers might cause unintentional errors.

The researchers modified their Logical Dynamical Decoupling sequences to resist crosstalk and other control issues. Employing “universally robust” sequence families and staggered pulses can reduce both logical and physical problems.Scientists say LDD sequences decrease physical and logical mistakes. This dual action boosted quantum computer efficiency, reducing postselection data rejection.

The Way Forward

Entangled logical qubits on a superconducting substrate reached their maximum fidelity in this study. It describes how to preserve “small and nimble” quantum codes that can withstand real-world noise.

The experiment focused on a distance-2 error detection code, however the scientists noted that the QEC-LDD Theorem they proved is universal. Utility-scale quantum algorithms use color and surface codes, which are theoretically applicable.

Overview

This paper proposes in situ deposited aluminum oxide passivation for superconducting microwave resonators to improve durability. To shield tantalum and aluminum surfaces from environmental degradation, researchers deposited this protective layer under ultra-high vacuum as the film grew. These passivated devices show negligible microwave loss and good quality after 14 months of air exposure, according to experiments. However, native oxide resonators performed poorly due to interfacial defects and chemical oxidation. Our results give a scalable technique to retain material chemical integrity for reliable superconducting quantum circuits.

Quantum Advancement via Superconducting Circuit Protection

Quantum computing has advanced significantly after a team of researchers from National Taiwan University (NTU) and National Tsing Hua University (NTHU) solved one of the most persistent “materials bottlenecks” in scalable quantum hardware. A new atomic-scale "shield" has allowed the scientists to show that critical superconducting elements can work well for almost 14 months in air. This extreme stability may enable long-lasting quantum processors.

Searching for Stability

Superconducting quantum circuits are promising quantum computer platforms. These circuits pair qubits and read quantum states using superconducting microwave resonators. These resonators perform best with a high internal quality factor (Qi), which measures microwave energy waste.

However, these parts are very delicate. As soon as exposed to oxygen, their surfaces produce "native oxides" as Ta2O5 and AlOx . These are commonly thin tantalum (Ta) or aluminum films. These oxides may appear protective despite being permeable and physically defective, according to sources. O2 and moisture slowly permeate these oxides, forming two-level systems (TLSs), small defects that absorb microwave radiation and quickly degrade device performance.

The Universal “In Situ” Solution

Yi-Ting Cheng, Minghwei Hong, and Jueinai Kwo led the research team to develop a global in situ passivation strategy to combat this “aging” effect. This novel method prevents oxides from developing, unlike standard methods that clean or etch them away.

A multi-chamber ultra-high vacuum (UHV) system generates tantalum and aluminum epitaxial films on atomically pure sapphire substrates. After the superconducting metal forms, the researchers install a 2–3-nanometer covering of amorphous aluminum oxide (Al2O3) without breaking the vacuum.

The researchers' study states that “this approach offers three key advantages,” including chemically clean surfaces, contamination-free interfaces, and a thick capping layer that prevents environmental deterioration.

Fourteen months of best results

Study results are outstanding. The researchers made microstrip resonators using their innovative passivation process and compared them to native oxide devices.

Both resonators initially had internal quality factors above one million (106). Performance changed dramatically over time. Resonators insulated by the in situ Al2O3 layer showed no degradation after 14 months of air exposure. Qi reduced considerably in native oxide tantalum resonators after two months. Aluminum deteriorated faster; unprotected Al resonators lost an order of magnitude in two weeks.

The scientists utilized XPS to analyze the films' chemical makeup to figure out why the shield worked so well. XPS tests showed that the in situ Al2O3 layer prevented the superconducting metal from oxidizing for months.

The Scalability Path

This innovation overcomes a major quantum technology scaling challenge. Large-scale quantum computer components must be made utilizing complex, multi-step processes that may involve storage or transport. Equipment must be sturdy during realistic “storage and transportation” stages.

Bloq, a quantum computing software and corporate infrastructure innovator, joined IBM Quantum Network. In early 2026, this alliance seeks to bring quantum technology from experimental research to “utility-scale” applications in high-impact areas like banking, logistics, automotive, healthcare, and material science.

Strategic Move into Utility-Scale Quantum Computing

The cooperation aims to create and improve quantum algorithms for IBM's latest utility-scale quantum processors. This shift to “utility-scale” follows IBM's 2023 demonstration that quantum processors with more than 100 qubits may produce exact results comparable to the most powerful classical approaches. By 2026, these platforms are the industry standard for algorithm development.

Bloq may access IBM's world-class quantum computers, including the recently unveiled IBM Quantum Nighthawk and Quantum Heron, via the cloud as a network member. These systems support Bloq's high-performance software stack with well-designed hardware for circuits with more complexity and reduced error rates.

Democratizing Quantum: Quantum Computing

Bloq, often known as the “quantum platforms,” is noted for its “Quantum for the Masses” approach. Researchers and developers can design complex quantum circuits using the company's low-code/no-code interface without a PhD in quantum physics.

This cooperation strengthens Bloq's platform integration with IBM's open-source quantum software stack, Qiskit. This integration gives Bloq users several technological advantages:

IBM hardware executes algorithms with automated error mitigation.

Custom circuit optimization for Heron and Nighthawk chips' heavy-hex lattice topology.

Qiskit Functions automates circuit knitting and sophisticated error suppression so developers may focus on business logic.

Bloq Quantum co-founder and CTO Jay Patel says this “dual-track strategy” develops a smooth platform and useful algorithms. It's claimed that Bloq's end-to-end development environment can accelerate data to quantum deployment by ten times.

Overcoming Global Issues

The cooperation is expected to solve several high-impact problems that traditional computers cannot:

Financial Optimization: Predictive and fast Monte Carlo simulations for risk and portfolio optimization.

Logistics and Supply Chain: Quantum-enhanced heuristics for exponentially complex scheduling and routing problems. Sustainable Materials: Simulating molecular electrical structures to improve carbon capture catalysts and battery technology.

Healthcare and automotive: Developing algorithms for fast-changing industries.

IBM Quantum Adoption and Business Development VP Bloq's enterprise-grade software and accessibility make it a great partner for fault-tolerant quantum computing, according to Scott Crowder.

Enhancing India's Quantum Ecosystem

Bloq's IBM Quantum Network membership is momentous for Indian tech. This prestigious international ecosystem includes only three Indian companies, including Bloq. Bloq offers a single workspace for the whole quantum lifecycle, from initial data processing to quantum processing unit (QPU) execution, to help Indian and global enterprises convert to quantum processes.

2029 Roadmap: Fault-Tolerance and Beyond

The 2026 IBM hardware roadmap anticipates Quantum Kookaburra. Kookaburra may be IBM's first modular processor with encoded data processing and storage. It will be crucial to 2029 fault-tolerant systems.

Bloq is joining the network immediately to prepare its clients for these future technologies. CEO Sreekuttan Lalimol Sukesh says Bloq wants its software and algorithms to be “battle-tested” and ready to give immediate value when technology is ready for 1,000-gate depth operations.

Introduction

In this paper, the MZLC protocol (Multi-Z-Line Control) is introduced to identify and resolve magnetic flux crosstalk in superconducting quantum processors. Flux control lines can unintentionally modify nearby qubit and coupler frequencies in complex multi-qubit systems, reducing gate fidelity and calibration precision.

By mapping interactions and employing a cancelation matrix, the authors reduce crosstalk from over 50 to virtually zero statistical error. Even with modest signal quality and poor readout equipment, this strategy scales quantum technology well. The study shows that decreasing these errors makes two-qubit gate operations more predictable, making larger, more durable quantum computers easier to build.

Challenge of “Quantum Cross-Talk”

Quantum computers' superconducting qubits compute with precise magnetic control. To construct fault-tolerant quantum computing, scientists must connect hundreds or thousands of qubits. “Flux crosstalk plays a role in a frequency-tunable qubit-coupler system; it obscures the precise frequency detuning required for a quantum gate operation,” the researchers said. Magnetic flux crosstalk increases with qubit density and Z-line density.

When a signal is sent to tune one qubit, the magnetic field leaks into surrounding qubits or couplers, causing unwanted frequency changes. As the system grows, this interference affects gate performance and makes proper calibration nearly impossible.

New standard: Multi-Z-Line Control

The study team, coordinated by Chung-Ting Ke and Myrron Albert Callera Aguila, developed Multi-Z-Line Control to describe and suppress this interference. MZLC uses residual inductive coupling between parts, unlike prior methods that required complex, specialized circuitry for each component.

Innovative characteristics of the study include Indirect Coupler Spectroscopy (ICS). “Tunable couplers” manage qubit interactions in a conventional quantum device. These couplers require driving lines and readout resonators, which take up chip space. The team's ICS technique avoids this by exploiting the coupler's weak capacitive coupling to nearby qubit driving lines. By letting researchers “see” what the coupler is doing without wire, the chip architecture becomes more scalable and compact.

From 56.5 to Zero: Precision Masterclass

The MZLC technique yields remarkable results. Researchers assessed average flux crosstalk levels before applying their proposed rectification methods. By establishing a cancelation matrix, a mathematical map that tells the system how to “counter-act” leakage, they reduced Z-line crosstalk from 56.5 to 0.13.

This considerable drop makes the remaining crosstalk practically statistical error. This accuracy ensures flux pulses, which regulate qubit frequency, become “decoupled, uniform, and reciprocal”.

Quantum Gates' “Digital Twin”

The MZLC protocol makes quantum gate operation more intuitive than noise dampening. These methods allowed researchers to develop a “digital twin” of the coupler-mediated conditional-phase (CZ) gate.

Complex quantum computing methods require a two-qubit CZ gate. By performing flux correction, the scientists created a perfectly symmetric map of CZ gate data. Researchers may accurately predict the gate's behavior and identify non-idealities such flux transients and undesirable mode hybridization using this digital twin.

The paper states that “Flux crosstalk compensation creates a magnetic flux crosstalk-free intuitive digital twin of the coupler-mediated CZ gate,” thus hundreds of qubit computers can optimize operations.

Effect on Future Computing

This discovery has far-reaching effects outside the lab. A “simple, scalable, robust, and low-overhead tool,” the MZLC protocol overcomes one of the primary engineering “bottlenecks” for superconducting computers of the size. Quantum computers will be able to solve problems that ordinary supercomputers cannot by maintaining high-fidelity gates as control lines increase.

Academia Sinica, National Taiwan University, Feng-Chia University, and National Changhua University of Education materials science, electrical engineering, and physics experts collaborated on the project. The Taiwanese National Science and Technology Council (NSTC) and National Quantum Initiative funded the research, showing the region's commitment to leading computing technology.

Cryo-CMOS for Quantum Computing

Finland's SemiQon, a premier quantum technology business, has entered a high-growth phase with the launch of its next-generation silicon-based quantum chip and a large cryogenic electronics manufacturing expansion. Turning three, the company went from a four-founder spin-off of the VTT Technical Research Centre of Finland to a 30-person scale-up that can solve quantum computing's biggest commercialization problems.

Bridging Cryo-CMOS Scalability Gap

SemiQon's most recent announcement is around the launch of a silicon quantum device that can operate at cryogenic temperatures with very little electricity. The “scalability bottleneck” of quantum architecture is overcome by this technology. Because traditional data processing occurs at ambient temperature, current systems require sophisticated thermal connections to cryogenic qubits. This arrangement increases heat load and physical complexity as systems scale.

SemiQon's cryo-CMOS technology processes data close to qubits. SemiQon eliminates wire and room-temperature control infrastructure by incorporating cryo-optimized transistors and circuits directly into chips, lowering prices, energy use, and physical volume.SemiQon CTO and creator Janne Lehtinen stated their first device will allow quantum computer makers to grow input/output capacity while substantially reducing energy consumption. This innovation changed the industry by making quantum computing a technical and production concern rather than a research-driven one.

Kvanttinova: A New Quantum Manufacturing Hub

SemiQon is moving to Kvanttinova, a cutting-edge facility being built in Otaniemi, Espoo, to facilitate the transition from research to mass manufacture. Compared to the Micronova plant, this move strategically triples the company's manufacturing capability.

Markku Kainlauri, SemiQon's founder and COO, said Kvanttinova is essential for scalable cryo-electronics production. From the new location, pilot lines and the Otaniemi ecosystem, which has helped the company grow quickly, will be conveniently accessible. The founder and chief research officer of SemiQon, Professor Mika Prunnila, calls the local research environment “transformative,” allowing a fast iteration cycle from concept to production and testing.

Financing Deep Tech's Future

SemiQon has grown rapidly with institutional and financial support. In early 2025, the European Innovation Council (EIC) gave the company €17.5 million in mixed investment. This €15 million equity funding and €2.5 million non-dilutive grant package was designed to help SemiQon commercialize its prototype products.

The company has earned industry honors for its concepts. EARTO (the European Association of Research and Technology Organizations) named SemiQon's cryo-CMOS technology, developed with VTT, the “Impact Expected” winner in October 2025. The award recognized the technology's potential to more than tenfold lower quantum readout system costs and volumes, enabling quantum hardware to data centers and cloud providers.

Commercialization Challenge: Quality and Resilience

A recent anniversary event brought together industry leaders to discuss “deep tech” product launches. David Gunnarsson, Bluefors' Chief Business Development Officer, says quality and dependability determine cryogenic industry commercial success. Despite early investors' hesitation, Bluefors' systems became industry standards by providing the research community with high-quality equipment over 18 years.

Arctic Instruments CEO Joonas Govenius stressed the balance between profit and R&D investment. “You can’t assume you’ll remain competitive three years from now without continuing to invest heavily in improving your product,” Govenius added.

SemiQon board chair Antti Vasara concurred, calling for more bold private financing in Europe. Vasara advised investors to invest in deep-tech companies early, before valuations soar.

The Finnish Ecosystem Collaboration Model

The Finnish semiconductor ecosystem has been a theme throughout SemiQon's growth. Tomy Runne of Murata Electronics advised the quantum sector to actively seek community participation, like Vaisala and Okmetic. He recounted how Murata directly engaged VTT to fix manufacturing challenges, which helped it expand internationally.

Pauliina Rajala, Development Manager at InstituteQ, said Finland's ambitious 10-year quantum technology goal can only be fulfilled with close collaboration across Europe.

Beyond Quantum Horizon Opportunities

Other high-stakes businesses are interested in SemiQon's cryo-optimized circuits, but quantum computing is the core target. Space technology and defense are growing markets because they need electronics that work in extreme cold. SemiQon's technologies increase power savings and cooling efficiency in space applications, where traditional electronics often fail.

Even with recent technical advances, Professor Mika Prunnila warned that disruptive technologies' long-term future remains unknown. He remembered how the CEO of Digital Equipment Corporation famously questioned whether people would want computers in their homes before the Commodore 64 sold millions of copies.Looking back is simpler than looking forward, Prunnila added.

SEALSQ Corp (NASDAQ: LAES), a global leader in semiconductors, Public Key Infrastructure (PKI), and post-quantum cybersecurity, has announced a significant second strategic investment in EeroQ. SEALSQ plans to use its “Quantum Made in USA” strategy to lead the global competition for secure and scalable quantum technology.

SEALSQ's SEALQUANTUM.com Quantum Investment Fund, founded in 2025, invested over $100 million in bootstrapping quantum startups. Following a December 2025 investment, this latest tranche shows a growing relationship between SEALSQ's secure silicon and post-quantum cryptography expertise and EeroQ's unique hardware.

Scalability Bottleneck Solution: EeroQ

This partnership relies on EeroQ's quantum architecture, which uses electrons trapped on superfluid helium (eHe). Unlike superconducting or trapped-ion devices, EeroQ's technique can scale from thousands to millions of electron spin qubits cost-effectively.

One of EeroQ's greatest technical achievements is solving the industry's “wire problem”. EeroQ has revealed a control architecture that can manage one million qubits with fewer than 50 physical control lines, whereas existing quantum implementations require thousands, causing thermal and engineering issues. EeroQ leads the way in commercial quantum processor development by reducing power dissipation and system complexity.

EeroQ's technology is also CMOS-compatible, thus it can be made using silicon chip industry fabrication methods. When combined with a tiny form factor that might make quantum processors as small as a thumbnail, this compatibility allows for rapid commercial adoption and infrastructure integration.

The “Quantum Highway”: Vertical Integration Vision

The Quantum Highway approach requires SEALSQ to invest in EeroQ, not merely for financial gain. This industry concept proposes a "Quantum Security Vertical Stack" to integrate post-quantum cryptography (PQC), classical computing, and future quantum processing safely and uninterrupted.

SEALSQ founder and CEO Carlos Moreira said, “This expanded investment in EeroQ represents a significant milestone in SEALSQ’s Quantum Made in USA strategy and in the establishment of a Quantum Highway.” EeroQ's hardware and SEALSQ's Quantum Shield QS7001 and VaultIC safe parts will be combined to create end-to-end systems for critical infrastructure, government agencies, and national defense.

To demonstrate this capability, the two companies aim to build a PoC at the SEALSQ Quantum Center of Excellence in Geneva. This platform will show how EeroQ's quantum processing technologies, post-quantum resistant systems, and secure semiconductor hardware integrate smoothly, giving enterprises a roadmap for future-proof infrastructures.

Emerging Global Footprint and “Quantum Corridor”

The “Quantum Made in USA” slogan promotes American sovereignty, yet SEALSQ is worldwide. This company has invested heavily in Europe and the US, putting resources along the Quantum Corridor:

Spain: SEALSQ and its parent company, WISeKey International Holding AG, have pledged $12 million and €20 million from the Spanish government's SETT.ES program to create a Post-Quantum Semiconductor Personalization and Test Center in Murcia.

Switzerland: PQC-secured blockchain identities will be integrated into enterprise and financial systems through a $3.5 million Group investment.

France: The purchase of top ASIC designer IC'ALPS is expected to speed up the production of customized, quantum-ready silicon.

WISeSat deployment cost $10 million.Space to launch a network of satellites for global encrypted communications following the quantum revolution.

Investment in ColibriTD attempts to boost semiconductor wafer yields using quantum power.

Future: Ethics, Engineering, and Financial Momentum A commitment to quantum ethics distinguishes EeroQ. According to SEALSQ's goal of establishing reliable, human-centric technological ecosystems, co-founder Faye Wattleton's company has been studying ethical frameworks for responsible quantum development since 2018. Technical leadership at EeroQ includes Princeton University professor CTO Steve Lyon and Chief Science Officer Johannes Pollanen, who just completed a 9,600-square-foot Chicago research and development center.

SEALSQ's strong financial performance reflects this strategy. Sales rose 66% in 2025, and cash reserves exceeded 425 million. By 2028, SEALSQ's commercial pipeline will exceed $200 million, suggesting market demand for secure and post-quantum semiconductor technology.

Despite the excitement, industry observers warn that technological and materials science challenges must be overcome before quantum systems can be widely employed commercially for years. By combining safe post-quantum cryptography with cutting-edge qubit architecture, SEALSQ is leading the cybersecurity-next-generation computing convergence.
