Deterministic entanglement of two neutral atoms via Rydberg blockade
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=0.580.04, which is above the entanglement threshold of F=0.5, without any correction for atom loss, and F=0.710.05 after correcting for background collisional losses. The fidelity results are shown to be in good agreement with a detailed error model.
