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…

Single-qubit rotations on a binomial code without ancillary qubits

Yuki Tanaka, Yuichiro Mori, Yuta Shingu +3

Great attention has been paid to binomial codes utilizing bosonic systems as logical qubits with error correction capabilities. However, implementing single-qubit rotation operatio…
