Towards high-fidelity control of thousands of individually trapped atomic qubits

Neutral atoms trapped in optical tweezer arrays have recently emerged as a leading quantum platform for the scalability and the high coherence that they offer. Scaling up to thousands of individually trapped atoms while preserving high coherence could open avenues in quantum metrology, quantum simulation and quantum error-correction. While state-of-the-art tweezer experiments have demonstrated the trapping of a thousand atoms, high-fidelity coherent control of several thousands of individually trapped atoms has yet to be realized.

Here, we report on progress towards global coherent control of cesium hyperfine qubits in optical tweezer arrays. We describe the challenges associated with controlling thousands of qubits, and how they could be overcome to achieve high single-qubit gate fidelity and competitive coherence times.
