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…
Experimental observation of chimera states in spiking neural networks based on degenerate optical parametric oscillators
Tumi Makinwa, Kensuke Inaba, Takahiro Inagaki +9
We experimentally demonstrate that networks of identical photonic spiking neurons based on coupled degenerate parametric oscillators can show various chimera states, in which, depe…
Collective and synchronous dynamics of photonic spiking neurons
Takahiro Inagaki, Kensuke Inaba, Timothée Leleu +7
Nonlinear dynamics of spiking neural networks has recently attracted much interest as an approach to understand possible information processing in the brain and apply it to artific…
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…
Experimental investigation of performance differences between Coherent Ising Machines and a quantum annealer
Ryan Hamerly, Takahiro Inagaki, Peter L. McMahon +20
Physical annealing systems provide heuristic approaches to solving NP-hard Ising optimization problems. Here, we study the performance of two types of annealing machines--a commerc…
