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…
