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…
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…
Spectroscopy of flux-driven Kerr parametric oscillators by reflection coefficient measurement
Aiko Yamaguchi, Shumpei Masuda, Yuichiro Matsuzaki +7
We report the spectroscopic characterization of a Kerr parametric oscillator (KPO) based on the measurement of its reflection coefficient under a two-photon drive induced by flux m…
