A microwave field is used to control the interaction between pairs of optical photons stored in highly excited collective states …
Quantum Lidar
In collaboration with the theory team lead by Prof. John Jeffers and supported by DSTL, we are developing new approaches to quantum enhanced LIDAR by creating a compact optical frequency comb source for pumping birefringent optical fibres and exploring a new log-likelihood metric to perform quantum enhanced stand-off detection and range-finding.
Hybrid atom-photon quantum gate in a superconducting microwave resonator
Physical Review A
