UK develops first quantum clock for military use

The project seeks to bolster military capabilities and drive progress across various sectors, with potential deployment anticipated within five years.

Quantum computing

The Ministry of Defence announced that the UK is developing its first quantum clock, a cutting-edge device designed to enhance military intelligence and reconnaissance. Created by the Defence Science and Technology Laboratory, the clock boasts unparalleled precision, losing less than one second over billions of years.

By leveraging quantum mechanics to measure atomic energy fluctuations, the technology reduces reliance on vulnerable GPS systems, offering greater resilience against disruption by adversaries. That marks the UK’s debut in building such a device, with deployment anticipated within five years.

While not the world’s first quantum clock (similar technology was pioneered in the US 15 years ago), the UK effort highlights a growing global race in quantum advancements. Quantum clocks hold potential beyond military applications, impacting satellite navigation, telecommunications, and scientific research.

Countries like the United States and China are heavily investing in quantum technology, seeing its transformative potential. Future UK research aims to miniaturise the quantum clock for broader applications, including integration into military vehicles and aircraft, underscoring its strategic importance in defence and industry.
