Tucson Conference funds seven ‘Game-Changing’ quantum teams

The Simons Foundation, Brinson Foundation, RCSA, and millionaire Kevin Wells announced the first Scialog: Quantum Matter and Information (QMI) grantees. This ambitious project seeks to bridge quantum science communities. 19 young academics from seven interdisciplinary teams will get funding for high-risk, high-reward investigations that could change our understanding of the quantum cosmos.

From October 16–19, 2025, 57 fellows from physics, chemistry, materials science, computer science, and engineering attended a rigorous four-day meeting in Tucson, Arizona. Over $1.1 million has been financed for the first year of the three-year project, with each winning researcher receiving $60,000 in direct costs.

Strategy for Quantum Exploration

Due to quantum research's revolutionary nature, RCSA President & CEO Eric Isaacs believes this Scialog could offer game-changing insights. QMI launched when the UN declared 2025 the International Year of Quantum Science and Technology, a turning point for the subject.

Isaacs contrasted recent Nobel Prizes to Fellows work. He noted that fundamental research in macroscopic quantum phenomena was recently awarded the Nobel Prize in Physics, demonstrating that this discipline is now crucial for computing and solving global problems. He linked the project to the Nobel Prize in Economics by citing creative destruction, where new technology drives long-term prosperity and transforms society and the economy.

Scialog—“science + dialog.”—aims to eliminate accidental discovery. The program brings together synthesis and systems experts to enhance predictable, rigorous experimental design.

Keynote: Fractional Charges to Gravitational Waves

Two conference keynote speakers set the tone for multidisciplinary collaboration. In his address, “The Angst and Ennui of Measuring Zero,” Rana Adhikari from the California Institute of Technology discussed the challenges of accurate measurement. Adhikari, a LIGO project leader, discussed the challenges of reducing systematic and random noise in gravitational wave detectors. He also noted the very high frequency of binary black hole detections compared to neutron star mergers and suggested using frequency-dependent squeezing and deep learning for feedback control.

Columbia University's Xiaoyang Zhu's second keynote talk was on “Fractional Charges and Where to Find Them”. Zhu calls time-domain pump-probe spectroscopy a “treasure map” for quantum phase location. He highlighted the discovery of similar phenomena in twisted bilayer graphene, which can show charges without magnetic fields. His research focuses on fractional charges created by high magnetic fields, like the fractional quantum Hall effect.

Consideration of Future

Funder collaboration was another key concern. Quantum research will likely benefit several scientific domains, according to Jamie Bender of The Brinson Foundation.

In search of the unseen, Axion Quasiparticles are solving the universe's biggest enigma.

A global team of scientists has found a new approach for discovering axions, the mysterious particles thought to make up most dark matter. Harvard, King's College London, Argonne National Laboratory, and other institutions contributed on the Nature study. Scientists believe quasiparticles are closer than ever to discovering a fundamental component of the universe undiscovered since the 1970s.

Elusive Axion and Dark Matter Puzzle

Axion has long been one of science's most sought-after fundamental particles, like the Higgs boson. Despite its widespread recognition in theory, the axion has never been observed. Its existence was postulated to solve particle physics and dark matter, which makes up 85% of the universe's mass, mysteries.

Conventional astronomy methods cannot detect dark matter because it does not emit, absorb, or reflect light. Besides solving the dark matter issue, axions would reveal the cosmos's genesis and evolution. A senior Argonne scientist, Ivar Martin, said prior attempts to discover these particles involved ingenious “light shining through the wall” tests or dark-matter axions being transformed into photons. However, the latest work uses quantum materials.

Quasiparticle “Simulated” Detectors

The breakthrough is due to quasiparticles, which are “particles” that are the aggregate behavior of many particles acting as a single unit rather than fundamental particles. The team produced a “material realisation” of axions in a lab in this experiment.

Despite their unique properties, these axion quasiparticles are deep space fundamental particle models. Harvard assistant professor Suyang Xu says a dark matter axion from the universe would excite the quasiparticle if it hit the carefully created material. Scientists can confirm dark matter axions in our environment by discovering this response.

“Cosmic Car Radio” tech

Manganese bismuth telluride, with its complex magnetic and electrical properties, underpins this discovery. To support axion quasiparticles, the researchers used precision nanofabrication engineering to mold the material into a two-dimensional crystal structure. To improve quantum characteristics, the material was carefully stacked.

The surgery was difficult. Lead author Jian-Xiang Qiu said manganese bismuth telluride is air-sensitive and difficult to work with. To modify its properties, the researchers had to “exfoliate” it down to a few atomic layers. The researchers used cutting-edge measurement tools and ultrafast laser optics to capture quasiparticle movements with unprecedented accuracy in a highly regulated environment.

Researchers call this system a “cosmic car radio”. As a radio may be tuned to capture a broadcast, this material can be tuned to axion particle radio frequencies. The team plans to use this “radio” to capture dark matter signals that have eluded all previous technology to detect dark matter within 15 years.

Multidisciplinary Success

The study succeeded because to an interdisciplinary approach that comprised condensed matter physics, material chemistry, and high-energy physics. Michael Smith and Ivar Martin of Argonne National Laboratory gave a detailed theoretical explanation of magnetic excitations to allow axion materialization.

The DOE Office of Science, the National Science Foundation, and many international organizations in Taiwan, Japan, Germany, India, and the UK supported the study. This international partnership shows how important the axion is to science. The amount of research being published on axions is comparable to before the Higgs boson was discovered, thus King's College London lecturer David Marsh says we are “closing in on the axion and fast”.

Going Beyond Dark Matter using Quantum Technology

Dark matter research drives this research, which influences quantum technology. The researchers showed axion quasiparticles' complex dynamics and cohesive behavior, paving the way for future technology. Martin and his colleagues are studying nonlinear optical phenomena enabled by the light-axion interaction.

A revolutionary quantum chemistry method to solve complex materials' mysteries

Localized Active Space

A new computational method for quantum chemistry was developed at the University of Chicago to reconcile physicists' and chemists' historically different perspectives on materials. By using the Localised Active Space (LAS) framework to periodic solids, this innovative method combines local quantum chemistry with global band theory to understand complex materials like organic semiconductors and high-temperature superconductors.

By accurately predicting local electronic activity and electron hopping across parts, the approach can predict how quantum mechanics affects transport characteristics in current materials. The researchers tested the technique on hydrogen chains and p–n junctions and believe it will be vital for developing high-quality materials in the future.

A University of Chicago computational method that combines two long-distance scientific viewpoints may help explain some of the world's most puzzling materials, from solar cell semiconductors to high-temperature superconductors. UChicago researchers may explain how quantum processes in contemporary materials cause transport properties.

Laura Gagliardi, senior author and Richard and Kathy Leventhal Professor in Chemistry at the Pritzker School of Molecular Engineering, says “chemists and physicists have used very different lenses to look at materials for decades.” “We have now developed a methodical approach to integrating those viewpoints,” she said, adding that this gives new tools to understand and build extraordinary materials.

Physicists study materials using huge, recurring band structures, while chemists study electrons in specific molecules or fragments. Metal-organic frameworks, organic semiconductors, and strongly correlated oxides are important materials that don't match either picture. Electrons in these materials jump between repeated fragments instead of being scattered.

Co-first author Daniel King said, “It is possible to accurately describe electrons on individual fragments, but you lose the global picture of how charges move across a material.” The new method squares the circle by modelling local fragments and recording electron hops.

The methodology is based on Research Assistant Professor Matthew Hermes' Localised Active Space (LAS) concept. Using the LAS framework for periodic materials, the researchers combined global band theory with local quantum chemistry.

The researchers tried the method in tough situations to prove its efficacy. Traditional density-function theory methods misclassify hydrogen chains as metals, making them difficult to predict. For more precise approaches, hydrogen chains must be insulators. The innovative Localised Active Space approach accurately showed how hydrogen chain electrons determine the material's insulator characteristics.

Another example was Localised Active Space simulation of a p–n junction, a vital feature of solar cells and computer processors. The technique successfully illustrated the previously difficult process of charges splitting and travelling across the junction when shown light.

Co-first author and fourth-year graduate student in the Gagliardi Group Bhavnesh Jangid called the findings “step one,” saying the technique accurately captures the correct physics. To improve the plan, the team will use various cutting-edge methods.

This method helps scientists understand and create novel materials. King says “at their core, all materials are quantum mechanical.” He noted that this is a significant step towards understanding how quantum mechanics drives everyday phenomena.

Schaibley is the first UA faculty fellow to unite quantum research.

John Schaibley

The University of Arizona Office of Research and Partnerships appointed John Schaibley as the first Quantum Faculty Fellow. Associate physics professor Schaibley. This new post was created to lead the university's quantum science and technology endeavours. Schaibley is an associate professor in the Wyant College of Optical Sciences and a Fellow at the University of Arizona Centre for Semiconductor Manufacturing.

John Schaibley will advise research senior vice president Tomás Díaz de la Rubia for three years. He wants to expand, strengthen, and organise the U of A's quantum research environment.

According to Díaz de la Rubia, the U of A's strength lies in its business relationships and researchers' expertise across subjects. Díaz de la Rubia aims to make Arizona a national leader in quantum technology, enabling advancements in semiconductor manufacturing, secure communications, and AI.

Schaibley's principal goal as a faculty fellow is to unite U of A quantum scholars into a centralised effort. He wants to create a leadership system that promotes college-wide creativity to advance quantum research.

John Schaibley said, “This is about how we strategically hire and develop quantum at the University of Arizona in a way that will make us excel in a unique way.”

He will lead campus lectures and a strategic planning process commencing in January 2026. Faculty on any quantum-related area will be asked to share ideas and identify opportunities to establish a long-term vision for the university's work. To “develop a quantum strategy that reflects the U of A’s distinct strengths and is in line with national and international priorities,” John Schaibley wants to “identify a central group of researchers.”

The U of A is well-positioned to study new quantum frontiers due to its strengths in innovative materials, acoustics, optics, and space research. These capabilities are supported by the New Frontiers of Sound (NewFoS) NSF Centre, which uses cutting-edge acoustic technology to recreate quantum phenomena, and the recently rebuilt ACA-sponsored Nano Fabrication Centre, which can make quantum devices.

John Schaibley said the national focus on quantum technology, artificial intelligence, semiconductor manufacturing, and fusion energy makes today “the perfect time” to expand the university's quantum efforts. He also credited the 2018 National Quantum Initiative Act for spurring investment and the establishment of quantum startup enterprises that offer cooperation and research opportunities. Because of their potential applications in space and quantum photonics, Schaibley supports cooperation to develop next-generation quantum devices and space-based quantum systems.

After receiving the $1.3 million, five-year Gordon and Betty Moore Foundation Experimental Physics Investigator Award, John Schaibley is conducting quantum research in addition to his fellowship. Schaibley's lab will use this money to produce synthetic quantum materials and engineer new quantum states in 2-D semiconductor devices.

These tiny crystals can regulate electron velocity and interaction to provide new, fundamental insights into condensed matter physics, including superconductivity and magnetism. This technology could make computers faster and more energy-efficient, reducing the energy footprint of massive data centres. It could be utilised for AI/ML and data security.

Researchers accelerate quantum computing at a $125 million U of A centre.

$125 million quantum center

University of Arizona's $125 million quantum research centre aims to accelerate quantum materials science, networking, and hardware advances in computing. The project intends to make the school a national quantum innovation centre as global competition increases. The team includes physicists, engineers, computer scientists, and industrial partners.

This year, the centre opened with cutting-edge labs, cooperative research areas, and rare quantum equipment. According to university authorities, the goal is to speed discoveries that could improve quantum processors, secure communication networks, and scientific understanding of quantum processes.

A Major Quantum Frontier Advance Qubits' behaviour in multiple states is used in quantum computing, unlike classical computing. Superposition allows quantum processors to perform exceedingly complex calculations tenfold faster than conventional machines in encryption, optimisation, and molecular modelling. Qubits are notoriously fragile and easily disrupted by heat, electromagnetic noise, and even tiny movements.

Researchers can test new qubit materials, hybrid quantum-classical systems, and error-correction methods at the U of A's quantum centre to address these longstanding difficulties. With the $125 million infusion, the centre can study superconducting circuits, trapped ions, photonics, and topological materials as qubit systems.

Dr. Lena Marwick, a physicist and centre researcher, advised blending numerous methods rather than committing to one. Marwick says one idea won't win the race to scalable quantum computing. A research ecosystem that can try multiple approaches, learn from them, and integrate the best answers is what we are constructing.

National Momentum and Strategic Positioning

Quantum technology is gaining popularity nationwide as the centre opens. Quantum technology is expected to transform many industries, so governments and corporations are investing billions in workforce development and infrastructure.

The National Quantum Initiative encourages universities to work with business, entrepreneurs, and national laboratories to innovate and commercialise, and the centre supports federal aims, universities say. In the U of A's funding paradigm, public funding and private donations from IT businesses working on next-generation quantum technologies are combined.

The institution intends to foster regional economic growth and scientific advancement by establishing Arizona at the forefront of this technological dynamism. The state plans to strengthen specialised manufacturing, cryogenics, optical engineering, and cybersecurity over the next decade to fulfil quantum technology demands.

Innovation-Boosting Facilities

Precision measurement suites, cryogenic facilities that can approach absolute zero, and quantum manufacturing laboratories are among the new center's most prominent characteristics. Superconducting qubits and nanoscale quantum state detectors are being developed.

Photonics research is another highlight of the institution. The teams there study photon routing and control for quantum networks. Since quantum information interceptions are observable, such networks may enable practically impenetrable communication systems.

The centre's simulation and algorithm development branch creates software systems for future quantum processors. This team collaborates with hardware teams to build application-ready solutions for early-stage quantum advantage in materials discovery, climate prediction, and logistics optimisation.

Student and Worker Development Centre Besides its scientific purposes, the $125 million centre will train future quantum scientists and engineers. University officials promoted new graduate fellowships, integrative courses, and practical labs to let students interact directly with cutting-edge quantum systems.

It is also expected that undergraduate researchers would be exposed to a subject that will create tens of thousands of high-skilled jobs in the US. Faculty believe involving students in research rather than classroom theory will help train them for future industry needs.

Industry Cooperation and Commercialisation Paths

The initiative prioritises industry ties. U of A teams have expressed interest in testing new gadgets, assessing materials, or designing prototype hardware together. Leadership at the centre expects these cooperation to lead to technological licensing, patents, and business startups.

To promote science, attract financing, and strengthen partnerships with national labs, the institution will organise frequent innovation seminars and demonstrations. These activities will help the centre become a significant quantum economy participant.

Future Outlook

A US$2.5 million DOE EPSCoR grant has boosted the University of Nebraska–Lincoln.

Nebraska Quantum Materials Research Faster With Grant

This funding infusion will build infrastructure and human resources for emergent quantum phenomena and enhance frontier quantum materials research.

It supports UNL's quantum materials research goals and is the third significant funding for the Emergent Quantum Materials and Technologies (EQUATE) Centre in recent months.

Ferroelectric Oxides and Interface Redesign

The grant's main focus is a study led by UNL physics and astronomy professor Xia Hong and a team of seven. Ferroelectric oxides, oxide, and van der Waals materials will be used to create quantum phases hitherto unattainable.

The team wants nanoscale control of ferroelectric processes in thin-film oxides to generate novel states of matter, such as reversibly switching between metal and insulator or magnetic and non-magnetic states. Hong said the goal is to use nanoscale ferroelectricity control to create a new state of matter to design smaller, more energy-efficient devices.

There are three main thrusts:

Exploring the potential for reversible quantum phase transitions (metal ↔ insulator; magnetic ↔ non-magnetic) at ferroelectric oxide and strongly-correlated oxide boundaries.

Integrating ferroelectric insulators into polar metals and multiferroic systems to store low-energy data by transitioning magnetic states with electric fields.

Ferroelectric thin-film superlattices and 2D van der Waals materials are stacked, rotation angles (Moiré engineering) adjusted, and domain structures altered to engineer new electrical and optical properties.

If successful, new smartphone and memory/logic device platforms may use less energy and perform better.

Infrastructure and Workforce: Two Investments

Besides science, the DOE EPSCoR award prioritises team training and infrastructure development. The two-year project may be extended to four years.

The project will fund early-career scientists at both schools and cooperate with South Dakota School of Mines & Technology. Early-career academics include Alexey Lipatov (SDSMT), Tula Paudel (SDSMT), and Zuocheng Zhang (UNL). Undergraduates, post-docs, and graduate students will participate.

“EPSCoR is looking into infrastructure and human resource development, not just research,” Professor Hong said.

The organisation intends to establish a long-term quantum materials science centre in the Midwestern US by improving its tools and workforce.

Nebraska's Quantum Materials Hub Gains Momentum

This grant builds on previous financing. Nearly five years ago, the NSF gave UNL $20 million to build the EQUATE Centre.

UNL researchers have obtained a $2 million NSF “Designing Materials to Revolutionise and Engineer Our Future” (DMREF) Grant and a $1.8 million NSF EPSCoR grant to develop innovative two-dimensional (“flatland”) materials.

Nebraska is becoming a quantum materials leader by focussing energy-efficient gadgets, next-generation electronics, and innovative materials research. This method is backed by multi-institution coalitions, academic leadership, and funding.

Expanding Technology and Society Implications Although the work focused on materials science and difficult physics, the implications are vast. Effective teamwork may yield:

High-efficiency devices that reduce computer power consumption.

Quantum-phase transitions replace semiconductor switching to provide quicker, smaller, and more powerful logic and memory systems. New 2D and oxide-membrane materials with programmable electrical and magnetic responses could revolutionise consumer electronics, memory storage, sensors, and quantum technologies.

A better regional quantum training and research environment for workforce readiness and new field innovation.

Hong said, “Even though you may not immediately see the impact, you are motivated by curiosity, the beauty of nature, and the fascination with how things behave.” That's the beauty of basic science.

What to Watch Next

The UNL team will focus on the three research thrusts' important milestones in the following years. Success will likely be measured by realistic device prototypes, scalable manufacture of new layered materials, and reversible quantum-phase switching demonstrations. Progress will also be shown by infrastructural growth and scientific training.

Based on its momentum and funding, Nebraska's EQUATE Centre might become a premier centre for quantum materials and devices, contributing to the national quantum information science, advanced electronics, and sustainable computing movement.

Quantum ISR

The continuously changing global strategic environment requires ISR capabilities for national security. In controversial fields, radar, SI, and electro-optics are reaching their physical and technical boundaries. ISR is threatened by GPS jamming, anti-satellite missiles, stealth weapons, and advanced electromagnetic countermeasures. To address this complexity, quantum technologies are poised to revolutionize airborne surveillance.

Transforming ISR Capability

Overhead surveillance has changed military history, from fragile airplanes taking aerial photos during World War I to reconnaissance satellites providing strategic overhead vision during the Cold War.

Today, skills are fundamentally changed rather than incrementally improved. Fahad ibne Masood argues in an opinion piece that quantum sensing and quantum-enhanced data analysis will be the next quantum ISR innovation. Extreme technology like cold-atom gravimeters, superconducting magnetometers, entangled photon systems, and quantum computers can practically eliminate battlespace uncertainty.

Improved Sensing with Quantum Phenomena

Quantum-powered By using coherence, entanglement, and superposition, ISR improves performance. These traits could let future sensors detect extremely weak magnetic or gravitational fingerprints. This function is crucial for finding targets buried behind ground clutter, camouflaged by electronic warfare activities, or in GPS-blocked regions.

New ISR capability relies on quantum-effect-based sensors:

Superconducting magnetometers detect industrial and automobile magnetic fields effectively.

Cold-atom Gravimeters: These instruments detect tiny gravitational field changes, making them useful for finding subsurface trenches or infrastructure.

Quantum entanglement, on the other hand, allows sensor networks to maintain correlation over long distances, while superposition lets particles study several measurement channels at once, increasing detection.

Quantum sensors are designed to detect irregularities that magnetometers and gravimeters cannot.

Sensing-Quantum Computing Integration

Improved sensing is crucial, but just half the recipe. The vast amounts of accurate data collected by these quantum sensors must be processed and merged immediately. Quantum computing may enable decision-making on timescales which traditional computers cannot. Sensing and analysis must be seamlessly integrated to reduce the “detection-to-action” cycle.

Significantly, the strategy aims for augmentation rather than replacement. By merging advanced quantum sensing modules with radar, electro-optics, and the tactical data connection, a modular, “plug-and-play” quantum layer will improve current systems' speed, accuracy, and robustness.

Airborne Validation and Rapid Progress

Quantum ISR is still young, but prototype devices and experimental testing are making headway, suggesting a move from lab displays to Airborne Research.

Recent field testing strengthen this momentum:

2023: Joint Base McGuire-Dix-Lakehurst field trials indicated Infleqtion's SqyWire quantum RF receiver had lower carrier-to-noise ratios than predecessors.

2024 (Air Force): A C-17 Globemaster III ran SandboxAQ's quantum magnetic anomaly navigation payload AQNav. Correlated high-band noise and atomic magnetometry made this device's positioning, navigation, and timing (PNT) robust in challenged conditions.

v2024 (Boeing): Boeing showed near-zero magnetic or inertial drift on a modified Beechcraft 1900 within four hours, demonstrating that quantum-based navigation technology is nearly mature.

2025: IonQ gave the Air Force Research Laboratory a quantum networking system, making integration of entangled sensor data across platforms easier.

Maturation and Technical Obstacles

Quantum sensors are limited in high-G, high-vibration flying. Drones and sensor platforms can fit 1–3 kilogram equipment that can withstand mechanical stress and rapid temperature fluctuations.

Too severe are cryostat and isolation chamber lab-scale quantum systems. Cryo-spray cooling systems, diamond-based magnetometry, and highly modular packaging to combine critical parts like control electronics and optical delivery into durable, compact modules are being studied.

An independent quantum sensor must smoothly connect with current Quantum ISR networks, synchronizing its timing, data, and capabilities with SIGINT, radar, and electro-optic systems.

Strategic Plan

If properly implemented, quantum ISR might transform U.S. defense. The ability to detect low-observable or buried targets in the face of electronic warfare and signal jamming; quick situational awareness from quantum computing analysis, which allows commanders to act more confidently and quickly; and less dependence on GPS offers alternate PNT methods in degraded or inaccessible environments.

But because the technology is young, maintenance, longevity, and dependability are risks. Adversaries may also develop quantum-resistant deception or stealth as technology progresses.

The need for quantum-enabled ISR is growing. This change requires collaboration between the Air Force, Army C5ISR centers, corporate partners, and academic labs. Financing and standards must last for interoperability.

What are subatomic particles?

Subatomic particles are needed to make qubits, the building units of quantum computing. Qubits, unlike classical bits, can exist as 0, 1, or both simultaneously through superposition and become fundamentally linked through entanglement using quantum processes inherent to these particles.

Using Subatomic Particles as Qubits

To represent the quantum states of ∣0⟩ and ∣1⟩, particles' spin or energy levels are adjusted. For as long as feasible, they are isolated to maintain their fragile quantum states.

Some subatomic particles and their uses:

Manipulating electron spin or other quantum states can make an electron a qubit.

The ∣0⟩ and ∣1⟩ states of photons, used as qubits, can be represented via time-bin encoding or horizontal or vertical polarisation. Photons are delivered through mirrors and beam splitters for quantum operations.

The loss or gain of electrons gives these atoms an electric charge. A vacuum's electric or magnetic fields hold them. Lasers control the ions' intrinsic energy levels, which are qubits. For quantum operations, these ions can be precisely moved and entangled.

Other Particles: Other subatomic particles or quantum systems are being studied to make qubits like quarks for quantum simulations of particle physics.

Key Quantum Phenomena Used

Quantum computers utilising subatomic particles can leverage strong quantum phenomena:

Superposition: Qubits, comprised of electrons and photons, can exist in many “0” and “1” states.

Getting entangled makes two or more qubits intrinsically linked. The status of one impacts the others immediately, regardless of distance. Quantum computers may study multiple possibilities and make complicated connections due to this interconnection.

Quantum computers excel at drug discovery, materials science, and complicated system simulations, where traditional computers fail. Their capacity to control entangled qubits in superposition allows them to compute enormous quantities of data in simultaneously and explore several solutions.

Subatomic Particle Qubit Benefits

Neutral atoms and trapped ions can be isolated well due to long coherence times. Due to their isolation, they can maintain their quantum state for a long period. This significantly reduces computation errors.

Quantum operations (gates) can be performed with exceptionally high accuracy and low error rates due to their inherent similarity and laser-controlled precision.

Even though scaling is a difficulty for all quantum computers, ion traps can be used to create larger systems by adding ions.

Subatomic Particle Qubit Drawbacks

Subatomic particles can maintain long coherence times, but they are sensitive to environmental noise including heat, magnetic fields, and stray light. Vacuum-controlled conditions must be maintained throughout the system.

Complex Infrastructure: Subatomic particle control is costly and difficult. They are difficult to create and run because they require a complex laser network, accurate vacuum chambers, and cryogenic refrigeration.
