Photonic Quantum Receiver Attaining the Helstrom Bound
Aakash Warke, Janis Nötzel, Kan Takase +6
We propose an efficient decomposition scheme for a quantum receiver that attains the Helstrom bound in the low-photon regime for discriminating binary coherent states. Our method,…
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…
Time-Domain Universal Linear-Optical Operations for Universal Quantum Information Processing
Kazuma Yonezu, Yutaro Enomoto, Takato Yoshida +1
We demonstrate universal and programmable three-mode linear optical operations in the time domain by realizing a scalable dual-loop optical circuit suitable for universal quantum i…
Programmable time-multiplexed squeezed light source
Hiroko Tomoda, Takato Yoshida, Takahiro Kashiwazaki +3
One of the leading approaches to large-scale quantum information processing (QIP) is the continuous-variable (CV) scheme based on time multiplexing (TM). As a fundamental building…
Continuous-variable quantum approximate optimization on a programmable photonic quantum processor
Yutaro Enomoto, Keitaro Anai, Kenta Udagawa +1
Variational quantum algorithms (VQAs) provide a promising approach to achieving quantum advantage for practical problems on near-term noisy intermediate-scale quantum (NISQ) device…
Building a large-scale quantum computer with continuous-variable optical technologies
Kosuke Fukui, Shuntaro Takeda
Realizing a large-scale quantum computer requires hardware platforms that can simultaneously achieve universality, scalability, and fault tolerance. As a viable pathway to meeting…
