Digital quantum simulations and quantum error correction protocols require the application of local gates. We demonstrate such local control in a neutral atom array platform by locally shifting the qubit's frequency using off-resonant light. We show precise, highly parallel, local Z-rotations with low crosstalk. Together with global X-rotations, which have been optimized for minimizing motional entanglement using optimal control, this approach can be used to locally implement universal single-qubit operations.
