Quantum nondemolition measurements via a two photon transition

Guojan Yang, Kaige Wang

We evaluate the effectiveness of a quantum-nondemolition measurement scheme in an effective two-level atomic configuration in the presence of the Stark shift. We compare the prediction of this model with that of its full cascade three-level counterpart and analyze the relationship between the quantum-nondemolition gain and the dynamic instability of the system.

We evaluate the effectiveness of the quantum nondemolition (QND) measurement scheme in an effective two-level atomic configuration by using the input–output formalism and the quantum regression theorem. The QND capability can be promoted greatly as the cavity detuning is swept towards the bistability threshold.
