Electron-Photon Spatial Entanglement in Coherent Cathodoluminescence
Tatsuro Yuge, Ryo Okamoto, Takumi Sannomiya +1
Electron--photon quantum entanglement in an electron microscope paves the way for a new quantum platform, enabling the integration of quantum functionalities into electron microsco…
Frequency correlated photon generation at telecom band using silicon nitride ring cavities
Zhenghao Yin, Kenta Sugiura, Hideaki Takashima +4
Frequency entangled photon sources are in high demand in a variety of optical quantum technologies, including quantum key distribution, cluster state quantum computation and quantu…
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…
0.54 μm resolution two-photon interference with dispersion cancellation for quantum optical coherence tomography
Masayuki Okano, Hwan Hong Lim, Ryo Okamoto +3
Quantum information technologies harness the intrinsic nature of quantum theory to beat the limitations of the classical methods for information processing and communication. Recen…
