Stabilization of Nonclassical States of the Radiation Field in a Cavity by Reservoir Engineering
Authors: A. Sarlette, J. M. Raimond, M. Brune, P. Rouchon, Physical Review Letters, Vol 107, no 1, ref 010402, July 1 2011, DOI: 10.1103/PhysRevLett.107.010402
We propose an engineered reservoir inducing the relaxation of a cavity field towards nonclassical states. It is made up of two-level atoms crossing the cavity one at a time. Each atom-cavity interaction is first dispersive, then resonant, then dispersive again. The reservoir pointer states are those produced by an effective Kerr Hamiltonian acting on a coherent field. We thereby stabilize squeezed states and quantum superpositions of multiple coherent components in a cavity having a finite damping time. This robust decoherence protection method could be implemented in state-of-the-art experiments.
