Observing a Phase Transition in a Coherent Ising Machine
Hiroki Takesue, Yasuhiro Yamada, Kensuke Inaba +8
A coherent Ising machine (CIM) is known to deliver the low-energy states of the Ising model. Here, we investigate how well the CIM simulates the thermodynamic properties of a two-d…
Low-loss polarization control in fiber systems for quantum computation
Tomohiro Nakamura, Takefumi Nomura, Mamoru Endo +5
Optical quantum information processing exploits interference of quantum light. However, when the interferometer is composed of optical fibers, degradation of interference visibilit…
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…
Non-Gaussian quantum state generation by multi-photon subtraction at the telecommunication wavelength
Mamoru Endo, Ruofan He, Tatsuki Sonoyama +12
In the field of continuous-variable quantum information processing, non-Gaussian states with negative values of the Wigner function are crucial for the development of a fault-toler…
