Experimental quantum-optics group at ANU led by Ping Koy Lam, working across continuous-variable (CV) photonic quantum information and rare-earth-doped solid-state quantum memories. The rare-earth thread (Eu:Y2SiO5, Pr:Y2SiO5, Er-doped crystals) has produced several of the field's longest coherent optical-storage demonstrations, positioning the platform as a candidate node for fibre-compatible quantum repeaters. In parallel the group runs CV squeezing, CV teleportation, and quantum-key experiments. Lam is also Chief Quantum Scientist at A*STAR (Singapore).
Current focus: Quantum optics and quantum communication
