Chaos in coupled Kerr-nonlinear parametric oscillators
Hayato Goto, Taro Kanao
A Kerr-nonlinear parametric oscillator (KPO) can generate a quantum superposition of two oscillating states, known as a Schrödinger cat state, via quantum adiabatic evolution, and…

Quantum Gate for Kerr Nonlinear Parametric Oscillator Using Effective Excited States
Taro Kanao, Shumpei Masuda, Shiro Kawabata +1
A Kerr nonlinear parametric oscillator (KPO) can stabilize a quantum superposition of two coherent states with opposite phases, which can be used as a qubit. In a universal gate se…
