Spin Model for Quantum Annealing with Kerr Parametric Oscillators

Leo Stenzel, Roeland ter Hoeven, Ryoji Miyazaki +3

Coherent states offer a promising path for near-term quantum computing due to their inherent protection against bit-flip noise. However, their large photon numbers can be challengi…

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…

Resonance fluorescence spectra of a driven Kerr nonlinear resonator

Aree Taguchi, Katsuta Sakai, Aiko Yamaguchi +11

Resonance fluorescence spectra of a driven Kerr nonlinear resonator is investigated both theoretically and experimentally. When the Kerr nonlinear resonator is driven strongly such…
