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…

Evaluation of graphene optical nonlinearity with photon-pair generation in graphene-on-silicon waveguides

Yuya Yonezu, Rai Kou, Hidetaka Nishi +4

We evaluate the nonlinear coefficient of graphene-on-silicon waveguides through the coincidence measurement of photon-pairs generated via spontaneous four-wave mixing. We observed…
