The UK’s Defence Science and Technology Laboratory (Dstl) has unveiled details of a new “groundbreaking” quantum atomic clock that will be deployable on military operations in the next five years.

The first device of its kind to be built in the UK, the lab said that the extremely accurate clock will be a “leap forward” in improving intelligence, surveillance, and reconnaissance by decreasing the reliance on GPS technology, which can be disrupted and blocked by adversaries via jamming.

The applications of quantum clocks extend beyond precise timekeeping, as the clocks can also be used to secure communication systems, such as encrypted military networks, which depend on highly-synchronised timekeeping.

Additionally, they can enhance the accuracy of advanced weapon systems, like guided missiles, which rely on accurate timing to calculate trajectories and coordinate attacks.

Trialling of the clock is the first time that Dstl has tested a UK-built optical atomic clock outside of a laboratory.

The trial involved key partners including Infleqtion (UK), Aquark Technologies, HCD Research, and Imperial College London, as well as in-house technology developed at Dstl’s quantum laboratory.

The development of the innovative technology supports key components of the UK Government’s Plan for Change, aiming to strengthen the country and improve the lives of its people.

Speaking on the advancement, Maria Eagle MP, the minister for defence procurement and industry, commented: “Integrating cutting-edge technology into existing capabilities exemplifies the Government’s commitment to innovation in the defence sector, and to ensuring our Armed Forces have the best kit possible to keep us secure at home and strong abroad.

“The trialling of this emerging, groundbreaking technology could not only strengthen our operational capability, but also drive progress in industry, bolster our science sector and support high-skilled jobs.”

Commander Matt Steele, the future technology officer for the Royal Navy’s office of the chief technical officer, also said: “The Navy has been looking at quantum technologies for a number of years and it is exciting to see that the challenges of physics and engineering in this area are now no longer a scientific concept, but is now reaching the cusp of reality.”

“In the next few years, the ability to operate effectively, to survive, and to navigate and also to remain lethal with the use of quantum alongside GPS will secure operational advantage.”
