| الوصف: | The nitrogen-vacancy (NV) center in diamond is a solid-state spin defect that has been widely adopted for quantum sensing and quantum information processing applications. Typically, experiments are performed either with a single isolated NV center or with an unresolved ensemble of many NV centers, resulting in a trade-off between measurement speed and spatial resolution or control over individual defects. In this work, we introduce an experimental platform that bypasses this trade-off by addressing multiple optically resolved NV centers in parallel. We perform charge- and spin-state manipulations selectively on multiple NV centers from within a larger set, and we manipulate and measure the electronic spin states of 10 NV centers in parallel. Further, we show that the high signal-to-noise ratio of the measurements enables the detection of shot-to-shot pairwise correlations between the spin states of 10 NV centers, corresponding to the simultaneous measurement of 45 unique correlation coefficients. We conclude by discussing how our platform can be scaled to parallel experiments with thousands of individually resolved NV centers. These results enable high-throughput experiments with individual spin defects, and provide a natural platform for the application of recently developed correlated sensing techniques.
