Broadband High-Level Squeezed Light using Waveguide Optical Parametric Amplifiers with External Dispersion Compensation
Takumi Suzuki, Shotaro Oki, Kazuki Hirota +8
We demonstrate broadband phase-sensitive amplification (PSA) measurement of squeezed light generated by a waveguide optical parametric amplifier (OPA) with external dispersion comp…
Localization of joint quantum measurements on by entangled resources with Schmidt number at most
Seiseki Akibue, Jisho Miyazaki
Localizable measurements are joint quantum measurements that can be implemented using only non-adaptive local operations and shared entanglement. We provide a protocol-independent…
Addressing requirements for crosstalk-free quantum-gate operation in many-body nanofiber cavity QED systems
Tim Keller, Seigo Kikura, Rui Asaoka +3
A distributed network architecture in which flying photons connect individual modules containing stationary atomic qubits is a promising approach for scaling up neutral-atom based…
Security of the BB84 protocol with passive biased basis choice by the receiver
Shun Kawakami, Atsushi Taniguchi, Yoshihide Tonomura +2
The Bennett-Brassard 1984 protocol (BB84 protocol) is one of the simplest protocols for implementing quantum key distribution (QKD). In the protocol, the sender and the receiver it…
Scalable Optical Quantum State Synthesizer with Dual-Mode Resonator Memory
Fumiya Hanamura, Kan Takase, Kazuki Hirota +12
Optical quantum computing is a promising approach for achieving large-scale quantum computation. While Gaussian operations have been successfully scaled, the inherently weak nonlin…
Optimizing Entanglement Manipulation via Algebraic-Geometric Decompositions and Semidefinite Programming Hierarchies
Seiseki Akibue, Jisho Miyazaki, Hiroyuki Osaka
In the study of distributed quantum information processing, it is a fundamental problem to optimize local operations in the implementation of non-local quantum operations assisted…
