We use the down-conversion process to generate quantum correlated signal and idler modes of light field. Assuming idler mode measurement of the produced state after a time t,we consider the evolution of the composite quantum-classical system of the two modes and of the detector. To have a unified formalism, we describe the detector like the third mode, where the number-state basis |n det>det is considered, but where the quantum superposition principle is not used and is not even allowed.
