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…

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…

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…
