Convergence and adiabatic elimination for a driven dissipative quantum harmonic oscillator
arXiv:1503.06324 · doi:10.1109/CDC.2015.7403235
Abstract
We prove that a harmonic oscillator driven by Lindblad dynamics where the typical drive and loss channels are two-photon processes instead of single-photon ones, converges to a protected subspace spanned by two coherent states of opposite amplitude. We then characterize the slow dynamics induced by a perturbative single-photon loss on this protected subspace, by performing adiabatic elimination in the Lindbladian dynamics.
