Over-8-dB squeezed light generation by a broadband waveguide optical parametric amplifier toward fault-tolerant ultra-fast quantum computers
Takahiro Kashiwazaki, Taichi Yamashima, Koji Enbutsu +6
We achieved continuous-wave 8.3-dB squeezed light generation using a terahertz-order-broadband waveguide optical parametric amplifier (OPA) by improving a measurement setup from ou…
Fabrication of low-loss quasi-single-mode PPLN waveguide and its application to a modularized broadband high-level squeezer
Takahiro Kashiwazaki, Taichi Yamashima, Naoto Takanashi +3
A continuous-wave (CW) broadband high-level optical quadrature squeezer is essential for high-speed large-scale fault-tolerant quantum computing on a time-domain-multiplexed contin…
All-optical phase-sensitive detection for ultra-fast quantum computation
Naoto Takanashi, Asuka Inoue, Takahiro Kashiwazaki +5
Phase-sensitive detection is the essential projective measurement for measurement-based continuous-variable quantum information processing. The bandwidth of conventional electrical…
