The Cryogenic Atom Array Gets a Universal Gate Set
A cesium array reported 99.970 percent single-qubit and 99.76 percent raw two-qubit gate fidelity in a cryogenic environment.
Summary
A cesium array reported 99.970 percent single-qubit and 99.76 percent raw two-qubit gate fidelity in a cryogenic environment.
Single-photon coupling to a Rydberg P state avoided the scattering and light shifts of a two-photon path. The measured error was dominated by atomic motion, while modeled Rydberg-decay contribution stayed below three in ten thousand.
Why it matters
A cesium array reported 99.970 percent single-qubit and 99.76 percent raw two-qubit gate fidelity in a cryogenic environment.
Limits and context
No additional limitation was separately recorded.
