Abstract
Section titled āAbstractāPhoton-mediated coupling between distant matter qubits may enable secure\ncommunication over long distances, the implementation of distributed quantum\ncomputing schemes, and the exploration of new regimes of many-body quantum\ndynamics. Nanophotonic devices coupled to solid-state quantum emitters\nrepresent a promising approach towards realization of these goals, as they\ncombine strong light-matter interaction and high photon collection\nefficiencies. However, the scalability of these approaches is limited by the\nfrequency mismatch between solid-state emitters and the instability of their\noptical transitions. Here we present a nano-electromechanical platform for\nstabilization and tuning of optical transitions of silicon-vacancy (SiV) color\ncenters in diamond nanophotonic devices by dynamically controlling their strain\nenvironments. This strain-based tuning scheme has sufficient range and\nbandwidth to alleviate the spectral mismatch between individual SiV centers.\nUsing strain, we ensure overlap between color center optical transitions and\nobserve an entangled superradiant state by measuring correlations of photons\ncollected from the diamond waveguide. This platform for tuning spectrally\nstable color centers in nanophotonic waveguides and resonators constitutes an\nimportant step towards a scalable quantum network.\n
