All-optical measurement-device-free feedforward enabling ultra-fast quantum information processing
Taichi Yamashima, Takahiro Kashiwazaki, Takumi Suzuki +8
Optical circuit systems, unlike other systems, have the potential to perform quantum information processing (QIP) at higher clock rate than conventional processing. The approach ut…
Quantum-enhanced optical phase-insensitive heterodyne detection beyond 3-dB noise penalty of image band
Keitaro Anai, Yutaro Enomoto, Hiroto Omura +4
Optical phase-insensitive heterodyne (beat-note) detection, which measures the relative phase of two beams at different frequencies through their interference, is a key sensing tec…
Generation of multi-photon Fock states at telecommunication wavelength using picosecond pulsed light
Tatsuki Sonoyama, Kazuma Takahashi, Tomoki Sano +9
Multi-photon Fock states have diverse applications such as optical quantum information processing. For the implementation of quantum information processing, it is desirable that Fo…
Optically-Sampled Superconducting-Nanostrip Photon-Number Resolving Detector for Non-Classical Quantum State Generation
Mamoru Endo, Kazuma Takahashi, Takefumi Nomura +11
Photon number-resolving detectors (PNRDs) are the ultimate optical sensors. Superconducting-nanostrip photon detectors (SNSPDs), traditionally known as ON-OFF detectors, have recen…
