| contents | We propose a novel non-destructive method for the detection of single Rydberg excitations in a mesoscopic ensemble. The protocol achieves high fidelities on a microsecond timescale and is robust against changes in the probe laser frequency. The technique relies on optical pumping in Autler Townes configuration, whose efficiency is controlled by the presence/absence of a Rydberg excitation. Taking rubidium atoms as an example, we give realistic estimates for the achievable fidelities and parameters. However, our protocol can be transferred to any other atomic species which features multiple stable states. Our protocol is applicable in quantum simulation and quantum information processing with mesoscopic ensembles requiring fast and high fidelity Rydberg state detection. |
