Towards high-fidelity parallel Rydberg two-qubit gates in large-scale optical tweezer arrays

Rydberg interactions in neutral atom arrays enable various applications in quantum computation, simulation, and metrology. In quantum computing, high-fidelity, scalable two-qubit Rydberg gates are essential for advancing error correction and realizing large numbers of logical qubits, a key requirement for practical fault-tolerant quantum computing. While experiments have demonstrated highly coherent single-qubit control over thousands of individually trapped atoms, realizing hundreds of parallel, high-fidelity two-qubit gates remains an outstanding challenge. Here, we report progress on addressing these challenges in large-scale atomic arrays, focusing on mitigating fidelity inhomogeneity and optimizing gate performance. Overcoming these challenges is critical for advancing neutral atom quantum computing and unlocking new possibilities in large-scale quantum systems.
