Infleqtion’s Quantum Timing Achieves 40x Improvement Over GPS, Validated on Quantum Corridor

Infleqtion has achieved a 40x improvement in timing precision over GPS, a breakthrough demonstrated on the Quantum Corridor, a dedicated fiber-optic network spanning 21.8 kilometers between Chicago and Hammond, IN. This leap forward, utilizing Infleqtion’s Tiqker quantum optical atomic clock, promises to bolster the security and resilience of critical digital infrastructure—from financial trading to AI—currently vulnerable to GPS disruption. “As digital infrastructure scales, relying on a single source of time is a growing risk,” said Pranav Gokhale, CTO at Infleqtion. This successful deployment over existing fiber, validated across a live urban network, signals a move towards quantum-based timing services and reduces dependence on potentially compromised satellite signals, paving the way for a new era of precise synchronization.

Infleqtion’s Tiqker Clock Achieves Picosecond Synchronization on Quantum Corridor

Infleqtion has demonstrated picosecond-level synchronization of its Tiqker quantum optical atomic clock across 21.8 kilometers of live urban fiber on the Quantum Corridor network, connecting Chicago’s ORD10 Data Center to a facility in Hammond, IN. This achievement marks a significant step toward bolstering the resilience of critical digital infrastructure currently reliant on vulnerable GPS signals. The demonstration utilized a purpose-built network, Quantum Corridor, engineered with tightly controlled parameters—a defined 1310–1550 nm single-mode fiber profile and a protected physical route—to preserve optical and temporal stability. The Tiqker clock, a rack-mounted system, maintained synchronization even amidst typical network activity and environmental fluctuations.

Measured results revealed up to a 40 times improvement over conventional GPS-based timing, and superior performance compared to cesium beam clocks, particularly over critical short to medium timescales. Patrick Scully, Chief Product Officer at Quantum Corridor, added, “This work shows that this can be deployed over an existing quantum-safe commercial network like ours to unlock a new class of timing performance.” This collaboration is paving the way for commercial quantum synchronization services, with Infleqtion planning to go public via a merger with Churchill Capital Corp X (NASDAQ: CCCX) in September 2025.

Engineered Fiber Network Enables 40x GPS Timing Improvement

This advancement relies on Infleqtion’s Tiqker, a rack-mounted quantum optical atomic clock deployed within the network’s infrastructure. The system maintained picosecond-level synchronization despite ongoing network activity and environmental fluctuations, highlighting its robustness.

A new 263-mile fiber-optic network, dubbed Quantum Corridor, is poised to redefine precision timing for critical digital infrastructure across the Midwest. This isn’t simply about faster data transfer; it’s about establishing a resilient and secure alternative to GPS-dependent synchronization, a vulnerability increasingly recognized as systems become more complex. This network, a member of the Bloch Tech Hub, is designed for high-bandwidth users like research institutions and defense contractors.
