Infleqtion Field Tests Optical Atomic Clock With US Navy
Infleqtion successfully field-tested its Tiqker optical atomic clock aboard a U.S. Navy support vessel for over two weeks during the Maritime Big Play Pacific exercise. The test, sponsored by the Office of the Under Secretary of War for Research & Engineering, involved the U.S. Navy, U.S. Marine Corps, and AUKUS partners from Australia and the UK. This trial offers one of the clearest indications that quantum timing hardware can operate effectively in challenging maritime conditions outside of a laboratory setting, though all performance claims originate from the vendor.
The Clock’s Performance at Sea
Infleqtion continuously operated Tiqker aboard the RV Merlin in the Southern California operating area. The operation also supported BARB-26, a Navy exercise focused on subsea and seabed warfare, which ran concurrently with the main MBP-P event. CEO Matthew Kinsella stated that this was “an important step toward validating quantum capabilities for real-world applications,” as per the company’s announcement.
The following details have been confirmed:
- Hardware: Tiqker, a compact, rack-mounted optical atomic clock that uses atomic optical transitions for timing reference.
- Duration: More than two weeks of continuous operation at sea.
- Platform: The U.S. Navy support vessel RV Merlin.
- Conditions: Exposure to significant temperature fluctuations and sustained vibration.
- Exercises: Maritime Big Play Pacific and BARB-26.
- Previous Trials: A 2025 trial aboard the UK Royal Navy’s uncrewed testbed XV Excalibur, and 2024 UK flight trials on QinetiQ’s RJ100 demonstrator with BAE Systems.
Infleqtion hasn’t disclosed specific measurements for accuracy, holdover duration during GPS denial, or power consumption. This lack of detailed metrics distinguishes a sea trial from proven operational readiness.
The Importance of Resilient Timing
Ships rely on precise timing for navigation, radar synchronization, and communication coordination. In scenarios where GPS signals are jammed or spoofed, satellite-derived timing becomes unreliable. A stable, independent local clock then serves as a crucial backup, ensuring systems remain synchronized. Infleqtion asserts that Tiqker can provide this independent reference for both manned and unmanned platforms, operating above and below the surface.
Accurate timing is also fundamental to secure infrastructure, including the cryptographic systems that governments are now transitioning to post-quantum standards, adhering to timelines such as the NIST IR 8547 deadlines. This connection is noted as a general principle, given that the demonstration focused on timing rather than encryption.
From Demonstration to Deployment
It remains unclear whether the Navy independently validated any of Tiqker’s performance metrics, or if this trial will lead to a recurring testing program or a path to procurement. For now, the result represents a vendor-reported demonstration supported by actual sea time, rather than a confirmed contract or a measured benchmark. We will continue to monitor developments.
