Serial-parallel conversion for single photons with heralding signals
Takayuki Kiyohara, Ryo Okamoto, Shigeki Takeuchi
We present serial-parallel conversion for a heralded single photon source (heralded SPS). We theoretically show that with the heralding signal, the serial-parallel converter can ro…
Nonlocal Position Changes of a Photon Revealed by Quantum Routers
Avshalom C. Elitzur, Eliahu Cohen, Ryo Okamoto +1
Since its publication, Aharonov and Vaidman's three-box paradox has undergone three major advances: i). A non-counterfactual scheme by the same authors in 2003 with strong rather t…
Implementation of a quantum controlled-SWAP gate with photonic circuits
Takafumi Ono, Ryo Okamoto, Masato Tanida +2
Quantum information science addresses how the processing and transmission of information are affected by uniquely quantum mechanical phenomena. Combination of two-qubit gates has b…
