Abstract
We propose simple experiments in cavity quantum electrodynamics leadin g, for the first time, to the measurement of negative values of the Wi gner function of an electromagnetic field. We also show that the reali zation of a controlled-not gate within the framework of cavity QED is a special case of our proposal, and is equivalent to the measurement o f the Wigner function of a one-photon field at the origin of phase spa ce.
