Measuring the quantum state of the electromagnetic field at finite temperature

Abstract We show that it is possible to reconstruct the quantum state of light in a cavity subject to dissipation at finite temperature. By passing atoms through the cavity it is shown that the decay does not prevent the measurement of s-parametrized quasiprobability distributions. Because such distributions contain whole information about the initial quantized field, it is possible to recover its complete information.
