Picosecond Schrödinger cat states for ultrafast optical quantum processing
Mamoru Endo, Kan Takase, Takefumi Nomura +12
Non-Gaussian states are essential resources for universal, fault-tolerant optical quantum computing, but their generation rate remains limited by low heralding probabilities and op…
Hybridization of pulse and continuous-wave based optical quantum computation
Tatsuki Sonoyama, Tomoki Sano, Takumi Suzuki +13
We propose a pulse and continuous wave (CW) hybrid architecture of continuous-variable measurement-based optical quantum computation utilizing the strengths of both pulsed and CW l…
High-Rate Four Photon Subtraction from Squeezed Vacuum: Preparing Cat State for Optical Quantum Computation
Mamoru Endo, Takefumi Nomura, Tatsuki Sonoyama +12
Generating logical qubits, essential for error detection and correction in quantum computation, remains a critical challenge in continuous-variable (CV) optical quantum information…
Erasing Photon-Number Correlations through Hong-Ou-Mandel Interference
Fabian Schlue, Patrick Folge, Takefumi Nomura +6
A parametric down-conversion source interfering on a beam splitter can be described as both a source of entangled N00N-states or a source of independent, and thus uncorrelated sque…
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…
