Direct measurement of quasiprobability distributions in cavity QED
Raúl Juárez-Amaro, H. M. Moya-Cessa · Physical Review A · 2003
We show that the set of s-parametrized quasiprobability distribution functions corresponding to an electromagnetic field in a cavity subject to dissipation can be directly measured. Such distributions contain whole information of the quantum state, therefore making it possible to recover information after losses have occurred.
