Akira Furusawa's group is the leading experimental continuous-variable (CV) photonic quantum-information laboratory in Japan. The team demonstrated the first unconditional CV quantum teleportation in 1998 (Furusawa et al., Science 282, 706, with the Caltech Kimble group) and has since defined the CV photonic line of work — squeezed-light sources, large-scale time-domain-multiplexed cluster states, and Gottesman–Kitaev–Preskill (GKP) encoded qubits for fault-tolerant photonic computing. The group anchors the Japanese CV-photonic-QC programme and runs a parallel commercialisation track through RIKEN.
Current focus: Optical continuous-variable quantum information
