Heralded Entanglement between Atomic Ensembles: Preparation, Decoherence, and Scaling
Abstract
Heralded entanglement between collective excitations in two atomic ensembles is probabilistically generated, stored, and converted to single-photon fields. By way of the concurrence, quantitative characterizations are reported for the scaling behavior of entanglement with excitation probability and for the temporal dynamics of various correlations resulting in the decay of entanglement. A lower bound of the concurrence for the collective atomic state of 0.9±0.3 is inferred. The decay of entanglement as a function of storage time is also observed, and related to the local dynamics.
