Entanglement of neutral atoms using Rydberg blockade

POSTER

Abstract

We report measurements of entanglement of two Rb atoms achieved with a Rydberg blockade mediated quantum gate. The entanglement fidelity is compared for two different gate protocols: one based on a Hadamard-$C_Z$-Hadamard sequence, and the other using a controlled amplitude swap operation. Entanglement fidelity $F>0.5$ is achieved after correction for atom loss during the gate operation. Progress towards deterministic entanglement, without correction for atom loss, will be presented.
