Israeli quantum technology company Quantum X Labs has announced a breakthrough in the development of its atomic clock technology, demonstrating a high-sensitivity system based on its proprietary Ramsey Coherent Population Trapping (Ramsey-CPT) platform.
The company said the system achieved short-term fractional frequency stability of 1 × 10⁻¹³ at one second, highlighting its potential for compact, high-performance timing solutions and future chip-scale atomic clocks.
Atomic clocks are considered a critical technology for resilient positioning, navigation, and timing (PNT), particularly as defense organizations seek alternatives to GPS-dependent systems vulnerable to jamming, spoofing, and other disruptions. Precise timing is essential for military platforms, autonomous systems, secure communications, and aerospace applications.
Quantum X Labs said its Ramsey-CPT technology could enable smaller and more robust atomic timing systems capable of operating in GPS-denied or contested environments. Potential applications include unmanned systems, defense platforms, telecommunications networks, data centers, and critical infrastructure.
The company explains that this development comes as militaries worldwide invest in next-generation timing technologies, including initiatives focused on maintaining synchronization in environments where traditional GPS signals cannot be relied upon.
Prof. Nir Sharon, chief scientist of Quantum X Labs, said the atomic clock is part of the company’s broader quantum sensing strategy, which also includes optical gyroscopes and inertial sensing technologies.
Quantum X Labs said it will continue efforts to improve performance, miniaturize the system, and advance integration toward deployable quantum timing solutions.
