    "abstract": "We present a scheme to reconstruct the quantum state of a field prepared\ninside a lossy cavity at finite temperature. Quantum coherences are normally\ndestroyed by the interaction with an environment, but we show that it is\npossible to recover complete information about the initial state (before\ninteraction with its environment), making possible to reconstruct any\n$s$-parametrized quasiprobability distribution, in particular, the Wigner\nfunction.",
