Change in bit-flip times of Kerr parametric oscillators caused by their interactions
Yuya Kano, Yohei Kawakami, Shumpei Masuda +8
We experimentally investigate how interactions between Kerr parametric oscillators (KPOs) degrade their bit-flip times, where a bit flip is defined as a transition between the two…

Four-body interactions in Kerr parametric oscillator circuits
Yohei Kawakami, Tomohiro Yamaji, Aiko Yamaguchi +9
We theoretically present new unit circuits of Kerr parametric oscillators (KPOs) with four-body interactions, which enable the scalable embedding of all-to-all connected logical Is…

Quantum annealing in capacitively coupled Kerr parametric oscillators using frequency-chirped drives
T. Yamaji, S. Masuda, Y. Kano +7
We study parametric oscillations of two capacitively coupled Kerr parametric oscillators (KPOs) with frequency-chirped two- and one-photon drives. The two-KPO system adiabatically…
