State preparation via quantum coherence and continuous measurement.
Additional Document Info
The theory of continuous measurement is generalized so as to be applicable to a two-mode radiation field whose properties are monitored by using a system with initial coherence between two ground states. The two-mode system is shown to offer the possibility of generating a number of new quantum states. Quantum statistics of the field following continuous measurements is calculated. Results for the phase distribution, quasiprobability distribution, and the photon-number distribution of the resulting field are also presented. 1994 The American Physical Society.
