Quantum Stochastic Dynamics in Multi-Photon Optics
Abstract
In this work a generic model of multi-photon optics is studied. It is considered m pump and n subharmonic fields. It shows how the multi-photon system, with direct and homodyne detection, can be obtained rigorously in the context of Measurement theory in Open Quantum System (see Bar-OQS, Bar-1990-QO and RCS-LAP). This is done trough the Quantum Stochastic Differential Equations with unbounded coefficients (see Fagnola-Wills, and RCS-LAP). In particular the existence of the dynamics is proved, and a continuous measurements scheme is provided.
