Overview

Indiana Quantum Corridor and Infleqtion conducted a successful technological trial to create very exact quantum time without GPS satellites. Using a fiber-optic network and a unique optical atomic clock called Tiqker, the partnership achieved faster synchronization speeds than satellite-based solutions. GPS interference and signal jamming can destroy critical digital infrastructure. The breakthrough is important in banking, telecommunications, and defense since accurate timekeeping is crucial for operational stability. Final example: adding quantum-grade precision to metropolitan networks for secure and resilient international communications.

Chicago-Indiana Quantum Corridor and Inflection

Infleqtion and Indiana Quantum Corridor announced the completion of a GPS-free quantum timing live demonstration, a major digital infrastructure milestone. The test showed a novel way to synchronize essential systems over 21.8 kilometers of live urban fiber with 40 times the accuracy of GPS-based alternatives.

The experiment connected Hammond, Indiana's Digital Crossroad Data Center to Chicago's ORD10 Data Center (350 Cermak), signaling a dramatic change in worldwide networks' time handling. GPS satellite dependency is becoming a systemic weakness as digital systems get more complex.

Limits of Invisible Utility

Often ignored, time is the “invisible utility” that fuels modern life. National security systems, AI networks, data centers, and high-speed financial trading platforms need perfectly synchronized clocks. Most of these systems use GPS.

Unfortunately, GPS signals are notoriously fragile.

Experts call them a “single point of failure” for key infrastructure because atmospheric conditions or deliberate interference can jam, spoof, or disrupt them. Pranav Gokhale, CTO of Infleqtion, says relying on one source of time becomes riskier as digital infrastructure increases. The recent experiment shows that fiber-optic connections can send quantum-grade timing, which is more accurate than satellite-based time.

Rack-mounted quantum clock: Tiqker

The sturdy, rack-mounted quantum photonic atomic clock Tiqker from Infleqtion drives this invention. In contrast to the massive, delicate atomic clocks in national laboratories, Tiqker is designed for operational use.

During the live test, the Tiqker technology maintained picosecond-level synchronization on “dark fiber” on the Indiana Quantum Corridor. The clock remained accurate despite network switching events and environmental variables that generally degrade high-precision signals. In critical short to medium timeframes, the obtained findings outperformed GPS and traditional cesium beam clocks.

An OOP Superhighway

Special construction of the Quantum Corridor made the test successful. Quantum Corridor is a quantum communications network, unlike fiber. A well secured physical route and a predefined single-mode fiber profile between 1310 and 1550 nm ensure optical and temporal stability.

A 263-mile "quantum superhighway" is intended to be the largest US network of its kind. The technology lets defense contractors, research centers, and the Chicago Quantum Exchange securely share data. Quantum Corridor Chief Product Officer Patrick Scully said this relationship is laying the groundwork for next-generation digital system timing services.

Defense to Finance Implications for Industry Quantum-grade timing via urban fiber affects several vital industries:

Financial Services: Accurate timestamps for high-speed trading, where milliseconds can mean millions of dollars in opportunity or danger.

AI and data centers: organizing big, scattered computing systems that must operate together to handle AI workloads.

Telecommunications: Enhancing 5G and 6G network reliability. National security requires a "hardened," terrestrial time source for military equipment that can operate without satellite transmissions.

Infleqtion and Indiana Quantum Corridor are showing precision timing on a commercial network that carries regular traffic to establish it as a vital component of the digital economy.

Emerging Quantum Environment

This announcement is crucial for Infleqtion. The leading neutral-atom quantum technology firm makes quantum RF receivers, inertial navigation systems, and quantum computers like the fault-tolerant Sqale. In September 2025, Infleqtion announced it would merge with Churchill Capital Corp X to go public.

Midwest expansion by Quantum Corridor Inc. continues. The company is one of 31 U.S. Regional Innovation and Technology Hubs for quantum technologies and a significant partner in the Bloch Tech Hub, a government-industry collaboration.

Bard physicist received $500,000 to stabilize unstable quantum computers in the Hudson Valley.

Abhinav Prem, a Bard College physics assistant professor, received a prestigious two-year, $500,000 DOE research award, boosting the Hudson Valley's burgeoning “quantum footprint.” The award aims to solve quantum computers' inherent instability, one of science's biggest concerns. The project's main institution, Bard College, will receive $300,006, confirming its standing as a leading theoretical physics center.

Challenge of Quantum Fragility Scientific and engineering problems include creating devices that can maintain these sensitive states long enough to perform complex calculations. This is a difficult sector where “bold promises coexist with healthy skepticism,” as the goal of constructing a truly fault-tolerant system that regularly gives a real-world advantage has not yet been attained.

A Novel Approach: The “Runaway Train” Comparison Professor Abhinav Prem addresses stability difficulties with an innovative theoretical strategy. His work forces errors into predictable “paths,” rather than trying to block out all outside noise, which is physically demanding. Abhinav Prem uses mathematical symmetries and odd phases of matter to find and rectify errors before they threaten the system.

Abhinav Prem compares his technique to “building tracks for a runaway train” to illustrate this tough concept. The tracks constrain the "train" (the error) to a specific course so it cannot spread uncontrollably or harmfully. Predictable fault paths help build more resilient quantum structures.

Hudson River “Quantum Corridor” strengthening This research affects beyond Bard College laboratory. The research combines theoretical investigations with practical techniques for “near-term” devices. The research is supposed to have real ramifications for contemporary quantum technologies, not just theoretical.

The prize will also support future scientists by paying one Bard and one USC postdoctoral researcher. Our work supports the Hudson River's growing quantum knowledge. Sources say Abhinav Prem's work enhances the region's quantum footprint, which includes:

IBM Poughkeepsie quantum processes. The IBM Thomas J. Watson Research Center in Yorktown Heights conducts research.

Future Path Quantum computing is essential to the nation's scientific goals, as shown by the Department of Energy's sponsorship. There are still several barriers to building a reliable quantum computer. Building fault-tolerant computers with a “consistent real-world advantage” remains the community's top issue.

To make quantum computers a mainstay of modern business, Professor Abhinav Prem's work at Bard College must bridge advanced theoretical physics and practical engineering. The research focuses on machine stability and dependability to transition quantum computing from a fragile experimental field into a global innovation tool.

The Annandale-on-Hudson neighborhood celebrates, but the scientific community will wait to see if Abhinav Prem's “tracks” can stop quantum errors. The DOE's investment supports Hudson Valley theoretical frameworks for now.

Quantum Corridor, Toshiba International Corporation (TIC), and key regional partners successfully demonstrated the first cross-state Quantum Key Distribution (QKD) demonstration over a live, commercial carrier network in the US. This achievement changes worldwide cybersecurity. This breakthrough makes quantum-secured communication a high-performance, cross-state reality and proves its commercial viability.

The demonstration employed a crucial 21.8-kilometer piece of Quantum Corridor's active, high-capacity optical network. This link connected Chicago's ORD 10 Data Centre to Hammond, Indiana's Digital Crossroad Data Centre across the state line. Quantum encryption to physically connect Indiana and Illinois is a quantum networking breakthrough. It proves that strong, uncompromising security may easily be added to commercial communication infrastructure. This effective cross-state link marks the transition of quantum security from a futuristic concept to a deployable, current, and vital part of the digital world.

Quantum Security Must Be Urgent

This technological marvel marks a turning point in cybersecurity. Today, most digital defences employ public-key cryptography like RSA and ECC. These mathematical riddles work well now, but large-scale quantum computers could attack them in “Y2Q.” A powerful quantum machine might compromise 95% of the world's encrypted data within ten years, say experts. Private medical data, financial transactions, and national defence secrets are at risk.

Quantum key distribution solves this existential threat mathematically and empirically. Quantum physics powers QKD's cryptographic key creation and distribution. The basic principle is that observing a quantum state disturbs it. If an eavesdropper, called “Eve,” intercepts the quantum channel, the photons used to transport the key change physically. This disturbance alerts Alice and Bob, legitimate users, who immediately discard and replace the compromised keys. Theory says even the most advanced quantum computers cannot breach this security.

Unmatched Performance and Integration

Integration into the real world has been QKD's biggest challenge. QKD deployment requires making sensitive quantum technology work reliably, fast, and without interfering with the massive data volumes that modern commercial fibre optic networks handle. Toshiba and Quantum Corridor's recent cross-state demonstration shows that a workable, high-availability commercial backbone can solve this integration problem.

Technically, the cross-state link was a quantum-classical integration marvel. The test proved that Toshiba's multiplexed QKD technology worked properly. This system can send both high-speed data transmission and sensitive quantum key distribution signals over a single fibre optic line. This capability is essential for commercial adoption because it eliminates the costly need for a dedicated fibre network for quantum security operations.

With this enhanced quantum security layer, Ciena's Waveserver 5 800G coherent encryption modules worked. This showed that top classical networking equipment and quantum security solutions could work together. Field deployment performance exceeds expectations. The system achieved 1,500 kbps secure key rates. It also maintained 100% commercial network line-rate throughput. Importantly, the encrypted network flow had no packet loss during the 48-hour continuous test.

Ciena encryptions received quantum-generated keys directly. They powered strong AES-256-GCM encryption, the gold standard in symmetric cryptography. For maximum ephemeral security, new QKD keys were obtained and installed into the encryption modules every 90 seconds. This aggressive key rotation schedule shows the solution's scalability and commercial readiness by decreasing cyber-adversaries' window of opportunity.

Creating the Midwest Quantum Heartland

Quantum Corridor President and CTO Ryan Lafler stressed the accomplishment's immediate strategic importance. Lafler called the result “more than a technical win; it is a critical, tangible step towards realising a commercially scalable, quantum-safe communications fabric that is essential for the nation's defence, finance, and life science industries”. He also noted that this deployment's performance on a live, cross-state commercial network considerably minimises the risk of nationwide deployments.

This vital relationship is built on the Midwest's rapidly growing quantum environment. The Chicago Quantum Exchange (CQE) cooperation endeavour was its direct predecessor. It also received valuable input from a University of Chicago advanced graduate student, highlighting the value of local academics and business partnership.

Dr. Michael Manfra, Purdue University Quantum Science and Engineering Institute Director, stressed the value of this regional relationship. Dr. Manfra said this “marks a significant transition towards commercially viable secure quantum key distribution across state boundaries within the Midwest Quantum heartland.” The region is swiftly becoming a national leader in quantum technology development because to significant programs like the Bloch Tech Hub, of which Quantum Corridor is a key member.
