Abstract:

Various schemes for the determination of a single-mode cavity state from the photon statistics of the field both before and after an interaction with one or two level atoms is presented. The state vector from the measured statistics is calculated and its simplicity is shown. The number states and coherent states fall within the class that may be measured with one atom interaction while squeezed states and Schrodinger cats are within those states that may be measured with two atom interaction. The complexity of the data inversion or measured statistics increases as the number of interacting atom increases.
