|Title:||Recovering coherence from decoherence: A method of quantum-state reconstruction|
|Abstract:||We present a feasible scheme for reconstructing the quantum state of a field prepared inside a lossy cavity. Quantum coherences are normally destroyed by dissipation, but we show that at zero temperature we are able to retrieve enough information about the initial state, making possible to recover its Wigner function as well as other quasiprobabilities. We provide a numerical simulation of a Schrodinger cat-state reconstruction. [S1050-2947(99)00211-5].|
