10-GHz-clock time-multiplexed non-degenerate optical parametric oscillator network with a variable planar lightwave circuit interferometer
Yuya Yonezu, Kensuke Inaba, Yasuhiro Yamada +4
A coherent XY machine (CXYM) is a physical spin simulator that can simulate the XY model by mapping XY spins onto the continuous phases of non-degenerate optical parametric oscilla…
Observation of binary phase states of time-multiplexed degenerate optical parametric oscillator pulses generated using a nonlinear fiber Sagnac loop
Hsin-Pin Lo, Takahiro Inagaki, Toshimori Honjo +1
We generated time-multiplexed degenerate optical parametric oscillator (DOPO) pulses using a nonlinear fiber Sagnac loop as a phase-sensitive amplifier (PSA) where the pump and amp…
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…
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…
Boltzmann sampling for an XY model using a non-degenerate optical parametric oscillator network
Yutaka Takeda, Shuhei Tamate, Yoshihisa Yamamoto +3
We present an experimental scheme of implementing multiple spins in a classical XY model using a non-degenerate optical parametric oscillator (NOPO) network. We built an NOPO netwo…
