Japan-Denmark seminar @Copenhagen (Nov.2019)
Furusawa Lab attended a seminar at Niels Bohr Institute in Copenhagen as a representative of Japan. It was held in the historical room which is seen in the framed photo. We believe that quantum mechanics was born in the room. Prof. Furusawa sits at Niels Bohr's desk.
"Generation of time-domain-multiplexed two-dimensional cluster state" appeared in Science and we made a press release!! (Oct.2019)
Prof.Furusawa received Medal with Purple Ribon!!
Chosen as "Paper of the Week"
The 13th Japan-US Joint Seminar on Quantum Electronics and Laser Spectroscopy@Kanazawa, Japan (Sep.2018)
Continuous-variable entanglement on a chip
Experimental proof of nonlocal wavefunction collapse
for a single particle using homodyne measurements
Ultra-Large-Scale continuous-variable cluster states
multiplexed in the time domain
Deterministic quantum teleportation of photonic qubits by a hybrid technique
Quantum-enhanced optical-phase tracking
Teleportation of Schrodinger's cat wave-packets of light
We demonstrated deterministic quantum teleportation of photonic qubits for the first time. That is, photonic qubits are always teleported in each attempt, in contrary to the former probabilistic scheme.
Based on the continuous wave scheme, we achieved generation of arbitrary superpositions of zero- to three-photon-number states with 80% high-efficiency. In the same scheme we also generated the state required for the cubic phase gate, whose non-classicality has been verified .
We proposed a new architecture for optical quantum computation which can efficiently perform arbitrarily large-scale quantum computation with minimal optical components.
