Kuhn leads the Atom-Photon Connection group, working at the single-atom, single-photon level. Key research thrusts: (1) deterministic generation of indistinguishable single photons from single atoms in high-finesse cavities, with cluster-state production for one-way quantum computing; (2) development of integrated fibre-tip microcavities with small radius-of-curvature for >50% photon capture efficiency and direct fibre coupling; (3) single-photon quantum memories using cavity-coupled atom systems; and (4) optical trapping of single atoms in the Lamb-Dicke regime for quantum simulation and networking. The group uses reinforcement learning for optimal quantum control of atom-cavity systems.
