Engineered two-photon dissipative confinement of a Kerr-cat qubit using SISIS quantum circuit refrigerator
Shumpei Masuda, Tsuyoshi Yamamoto, Shuji Nakamura +2
Kerr-cat qubits realized in periodically driven superconducting nonlinear resonators are a promising platform for quantum information processing with biased noise. Pure dephasing i…

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…
