Randomized benchmarking of atomic qubits in an optical lattice

Understand

We perform randomized benchmarking on neutral atomic quantum bits (qubits) confined in an optical lattice.

• Single qubit gates are implemented using microwaves, resulting in a measured error per randomized computational gate of 1.4(1) x 10^-4 that is dominated by the system T2 relaxation time.
• The results demonstrate the robustness of the system, and its viability for more advanced quantum information protocols.
