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 study of the Spectroscopic measurements of Kerr non-linear resonators with four-body interaction
Yuichiro Matsuzaki, Yuichiro Mori, Aiko Yamaguchi +2
Quantum annealing provides a promising way to solve combinational optimization problems where the solutions correspond to the ground state of the Ising Hamiltonian. We can implemen…
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…
Suppression of decay widths in singly heavy baryons induced by the anomaly
Yohei Kawakami, Masayasu Harada, Makoto Oka +1
We study strong and radiative decays of excited singly heavy baryons (SHBs) using an effective chiral Lagrangian based on the diquark picture proposed in Ref. [1]. The effective La…
Single heavy baryons with chiral partner structure in a three-flavor chiral model
Yohei Kawakami, Masayasu Harada
We construct an effective hadronic model including single heavy baryons (SHBs) belonging to the representation under $\mbox{SU}(3)_L \times \mbox{SU}(3)_R…
Analysis of , , , based on a chiral partner structure
Yohei Kawakami, Masayasu Harada
We construct an effective hadronic model including , , and regarding them as chiral partners to , , and $Σ…
