An experimental quantum-optics researcher whose collaborative work spans continuous-variable teleportation and large optical cluster states, advancing routes to information processing with light.
RIKENFurusawa’s research explores how light can carry and process quantum information. His coauthored teleportation experiment demonstrated a central communication primitive for continuous-variable optical systems. Later work generated a two-dimensional cluster state using light arranged across time bins. These contributions connect individual quantum operations with the structured entanglement needed for a broader computing architecture, making his work a useful entry point into the possibilities and engineering challenges of photonic computation.

Work, in context- 1998
Continuous-variable quantum teleportation
Furusawa coauthored Unconditional quantum teleportation, an optical experiment published in Science. It demonstrated teleportation in a continuous-variable setting, establishing a practical quantum-information operation using light.
Coauthor of the optical teleportation experiment with Sørensen, Braunstein, Fuchs, Kimble and Polzik.
Source-supported recordRIKEN - 2019
An optical two-dimensional cluster state
Furusawa was a coauthor of the Science experiment generating a two-dimensional cluster state with time-domain multiplexing. The work developed a structured, extended entanglement resource relevant to optical measurement-based quantum computing.
Coauthor of the collaborative optical cluster-state experiment, not sole creator of its apparatus or result.
Source-supported recordRIKEN - 2021
Programming operations on optical cluster states
Furusawa coauthored a demonstration of quantum operations on time-multiplexed optical cluster states at a 25-MHz clock frequency. Dynamically changing the measurement basis connected an entanglement resource with programmable operations; the frequency is not a claim of computational advantage.
Coauthor of the optical quantum-operations experiment; the clock rate belongs to the reported experimental system.
