Generation and Preservation of Coherence in Dissipative Quantum Optical Environments
B. M. Garraway, P. L. Knight, Martin Bodo Plenio · Physica Scripta · 1998
We discuss the decay and decoherence of nonclassical states in quantum optics coupled to zero-temperature heat baths, and contrast ensemble behaviour with that of individual realizations. We show how nonclassical states are highly sensitive to dissipation in a number of cases, but present an example of how dissipation can be used to generate nonclassical states.
