Scalable Control of Over 100 Individually Resolved Nitrogen-Vacancy Centers in Diamond

ORAL

Abstract

Nitrogen-vacancy (NV) centers in diamond have emerged as versatile quantum sensors and qubits. However, conventional experimental architectures typically suffer from a trade-off between single-defect resolution and ensemble-scale throughput. We present an experimental platform enabling simultaneous control and readout of more than 100 individually resolved NV centers. By integrating high-speed optical addressing with global spin-state manipulation, we achieve parallel initialization, manipulation, and high fidelity readout of NV center charge- and spin-states with single-defect resolution. We leverage these capabilities to measure 5,000 unique pairwise electronic spin-state correlations at once. This platform is inherently scalable, with a path toward measurements with thousands of individual NV centers. These advances establish arrays of individual NV centers as a practical resource for large-scale quantum technologies, combining the precision of single-spin control with the statistical power of parallel operation.
