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…
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…
Real-time observation of picosecond-timescale optical quantum entanglement toward ultrafast quantum information processing
Akito Kawasaki, Hector Brunel, Ryuhoh Ide +10
Entanglement is a fundamental resource of various optical quantum-information-processing (QIP) applications. Towards high-speed QIP system, entanglement should be encoded in short…
High-rate Generation and State Tomography of Non-Gaussian Quantum States for Ultra-fast Clock Frequency Quantum Processors
Akito Kawasaki, Ryuhoh Ide, Hector Brunel +16
Quantum information processors greatly benefit from high clock frequency to fully harnessing the quantum advantages before they get washed out by the decoherence. In this pursuit,…
24-hour measurement of squeezed light using automated stable fiber system
Tomohiro Nakamura, Takefumi Nomura, Mamoru Endo +8
In order to provide a cloud service of optical quantum computing, it is inevitable to stabilize the optical system for many hours. It is advantageous to construct a fiber-based sys…
Generation of Flying Logical Qubits using Generalized Photon Subtraction with Adaptive Gaussian Operations
Kan Takase, Fumiya Hanamura, Hironari Nagayoshi +6
The generation of a logical qubit called the Gottesman-Kitaev-Preskill qubit in an optical traveling wave is a major challenge for realizing large-scale universal fault-tolerant op…
