UK Develops Quantum Clock To Cut Military GPS Dependence

Britain's Defence Science and Technology Laboratory has developed a quantum atomic clock that will lose less than one second over billions of years, the Ministry of Defence announced on Thursday.

The UK-built device aims to reduce military reliance on GPS technology, which can be disrupted by adversaries. It will be deployable in military operations within five years, supporting navigation systems, encrypted communications, and advanced weapons systems. The $34.6 million project involves partners including Infleqtion UK, Aquark Technologies, and Imperial College London. The clock was tested outside laboratory conditions for the first time in collaboration with the Royal Navy and Army Futures team.
