Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what progress has he made in developing a Quantum Radar capability.

Defence quantum experts within Defence Science and Technology (DST), the Defence Science and Technology Laboratory (Dstl), and Atomic Weapons Establishment (AWE) work closely with our international allies and partners in wider Government, industry and academia to support the UK’s world class expertise in quantum, and to identify and exploit the potential opportunities this developing technology can bring. Defence is a founding partner of the National Quantum Technology Programme (NQTP) and works closely with the NQTP, DSIT, Innovate UK and the UKRI quantum research activities.

‘Quantum Radar’ and ‘Quantum Illumination’ have specific meanings. In both cases the technology is immature and the potential benefits to Defence remain uncertain.

However, the Ministry of Defence (MOD) is conducting science & technology research into Quantum Technologies more broadly. This includes a focus on clock technology to enhance timing capabilities and sensing for navigation and situational awareness. Trials have been undertaken to understand the utility this technology can offer and inform technology development. MOD is collaborating with the UK’s Quantum Ecosystem, including the Quantum sensing, Imaging and Timing (QuSIT) Hub (led by the University of Birmingham) that is researching Quantum enhanced RADAR.

The particular focus and priorities of Defence research activity is classified and cannot be released for National Security reasons.
