A system for coherent site-resolved control of an array of neutral-atom qubits, part II

Individually-trapped neutral atoms are a promising technology for scalable quantum computation. Such systems offer high readout fidelity, control over excursions to Rydberg states for qubit interactions, and spatial manipulation of many-atom arrays. Here we present a method for achieving single-qubit control over individual atomic qubits confined in arrays of optical tweezers. This approach differs from previous implementations of single qubit control that required global addressing of the atomic ensemble; by leveraging advances in agile RF instrumentation we achieve phase and amplitude control of the light incident on each atom, giving access to full SU(2) control of the Hilbert space. Capitalizing on the long coherence times of strontium, we aim to scale this quantum control to arbitrarily large arrays of qubits in a parallelizable manner. Here, we demonstrate the coherent, site-resolved single-qubit manipulations of an array of neutral-atom qubits.
