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…

Generation of a time-bin Greenberger--Horne--Zeilinger state with an optical switch

Hsin-Pin Lo, Takuya Ikuta, Koji Azuma +3

Multipartite entanglement is a critical resource in quantum information processing that exhibits much richer phenomenon and stronger correlations than in bipartite systems. This ad…

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…

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…

Thermodynamic quantities of two-dimensional Ising models obtained by noisy mean field annealing and coherent Ising machine

Kensuke Inaba, Yasuhiro Yamada, Hiroki Takesue

Noisy mean field annealing (NMFA) is an algorithm that mimics a coherent Ising machine (CIM), which is an optical system for solving Ising problems. The NMFA has reproduced the sol…

Roadmap for Unconventional Computing with Nanotechnology

Giovanni Finocchio, Jean Anne C. Incorvia, Joseph S. Friedman +48

In the "Beyond Moore's Law" era, with increasing edge intelligence, domain-specific computing embracing unconventional approaches will become increasingly prevalent. At the same ti…
