Preparation of entangled and antiferromagnetic states by dissipative
Rydberg pumping    [PDF]

A. W. Carr, M. Saffman

We propose and analyze an approach for preparation of high fidelity entanglement and antiferromagnetic states using Rydberg mediated interactions with dissipation. Using asymmetric Rydberg interactions the two-atom Bell singlet is a dark state of the Rydberg pumping process. Master equation simulations demonstrate Bell singlet preparation fidelity $\mcF=0.998$. Preparation of antiferromagnetic spin plaquettes is also demonstrated.
