Large Fluctuations in Open Quantum Systems
V. Yu. Mylnikov, S. O. Potashin, A. Kamenev
We study statistics of atypical measurement outcomes in the steady states of driven open quantum systems. In equilibrium, the probability distribution over the phase space, as enco…

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…
