Abstract

We demonstrate the first deterministic entanglement of two individually addressed neutral atoms using a Rydberg blockade mediated controlled-NOT gate. Parity oscillation measurements reveal an entanglement fidelity of \$F=0.58\pm0.04\$, which is above the entanglement threshold of \$F=0.5\$, without any correction for atom loss, and \$F=0.71\pm0.05\$ after correcting for background collisional losses. The fidelity results are shown to be in good agreement with a detailed error model.
