Phase properties of macroscopic superposition states

Phase properties of states consisting of superpositions of the states mod a) and mod -a), coherent states of a single mode quantized electromagnetic field, are studied. These states are also known as macroscopic superposition states and 'Schrodinger cat' states. After first reviewing the squeezing and antibunching properties of these states, from the density operator and the phase states we derive a probability distribution for the phase. We also compare with this distributions obtained from the associated Q-function and the Wigner function.
