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…
Continuous-wave 6-dB-squeezed light with 2.5-THz-bandwidth from single-mode PPLN waveguide
Takahiro Kashiwazaki, Naoto Takanashi, Taichi Yamashima +5
Terahertz (THz)-bandwidth continuous-wave (CW) squeezed light is essential for integrating quantum processors with time-domain multiplexing (TDM) by using optical delay line interf…
4-dB quadrature squeezing with fiber-coupled PPLN ridge waveguide module
Naoto Takanashi, Takahiro Kashiwazaki, Takushi Kazama +4
We have developed an optical parametric amplification module for quadrature squeezing with input and output ports coupled with optical fibers for both fundamental and second harmon…
