Qubit decoherence in dissipative two-photon resonator: real-time instantons and Wigner function
V. Yu. Mylnikov, S. O. Potashin, Alex Kamenev
We study the quantum dynamics of a single bosonic cavity subject to two-photon driving and two-photon dissipation in the presence of finite detuning. Exploiting a hidden time-rever…

Switching rates in Kerr resonator with two-photon dissipation and driving
V. Yu. Mylnikov, S. O. Potashin, M. S. Ukhtary +1
We analytically investigate the switching rate in a two-photon driven Kerr oscillator with finite detuning and two-photon dissipation. This system exhibits quantum bistability and…
