Abstract: A detailed analysis of the diffusive Stochastic Master Equation (SME) forqubit/cavity systems with dispersive coupling is provided. This analysis incorporates clas-sical input signals and output signals (measurement outcomes through homodyne detec-tion). The dynamics of the qubit/cavity density operator is shown to converge exponen-tially towards a slow invariant manifold, parameterized via a time-varying deterministicKraus map by the density operator of a fictitious qubit. This fictitious qubit is governedby a SME incorporating the classical input/output signals. Extension where the qubit isreplaced by any qudit dispersively coupled to an arbitrary set of modes with collectiveinput/output classical signals.
