    "abstract": "We present a feasible scheme for reconstructing the quantum state of a field\nprepared inside a lossy cavity. Quantum coherences are normally destroyed by\ndissipation, but we show that at zero temperature we are able to retrieve\nenough information about the initial state, making possible to recover its\nWigner function as well as other quasiprobabilities. We provide a numerical\nsimulation of a Schroedinger cat state reconstruction.",
