Experimental Proof of Nonlocal Wavefunction Collapse for a Single Particle Using Homodyne Measurement
Maria Fuwa, Shuntaro Takeda, Marcin Zwierz +2
A single quantum particle can be described by a wavefunction that spreads over arbitrarily large distances, but it is never detected in two (or more) places. This strange phenomeno…
Entanglement swapping between discrete and continuous variables
Shuntaro Takeda, Maria Fuwa, Peter van Loock +1
We experimentally realize "hybrid" entanglement swapping between discrete-variable (DV) and continuous-variable (CV) optical systems. DV two-mode entanglement as obtainable from a…
Noiseless conditional teleportation of a single photon
Maria Fuwa, Shunsuke Toba, Shuntaro Takeda +6
We experimentally demonstrate the noiseless teleportation of a single photon by conditioning on quadrature Bell measurement results near the origin in phase space and thereby circu…
Optical Hybrid Quantum Information Processing
Shuntaro Takeda, Akira Furusawa
Historically, two complementary approaches to optical quantum information processing have been pursued: qubits and continuous-variables, each exploiting either particle or wave nat…
Equilibrium to nonequilibrium condensation in driven-dissipative semiconductor systems
Makoto Yamaguchi, Tetsuo Ogawa
Semiconductor microcavity systems strongly coupled to quantum wells are now receiving a great deal of attention because of their ability to efficiently generate coherent light by t…
Deterministic quantum teleportation of photonic quantum bits by a hybrid technique
Shuntaro Takeda, Takahiro Mizuta, Maria Fuwa +2
Quantum teleportation allows for the transfer of arbitrary, in principle, unknown quantum states from a sender to a spatially distant receiver, who share an entangled state and can…
