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…
Theoretical Analysis of Photonic Resonances in Spectroscopic Measurements of a Kerr Nonlinear Resonator
Yuki Tanaka, Aiko Yamaguchi, Tomohiro Yamaji +4
The Kerr parametric oscillator (KPO) has recently attracted considerable attention from the perspective of its applications to quantum information processing, and understanding its…
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…
