Query: Quantum interference of electromechanically stabilized emitters in
  nanophotonic devices   Photon-mediated coupling between distant matter qubits may enable secure
communication over long distances, the implementation of distributed quantum
computing schemes, and the exploration of new regimes of many-body quantum
dynamics. Nanophotonic devices coupled to solid-state quantum emitters
represent a promising approach towards realization of these goals, as they
combine strong light-matter interaction and high photon collection
efficiencies. However, the scalability of these approaches is limited by the
frequency mismatch between solid-state emitters and the instability of their
optical transitions. Here we present a nano-electromechanical platform for
stabilization and tuning of optical transitions of silicon-vacancy (SiV) color
centers in diamond nanophotonic devices by dynamically controlling their strain
environments. This strain-based tuning scheme has sufficient range and
bandwidth to alleviate the spectral mismatch between individual SiV centers.
Using strain, we ensure overlap between color center optical transitions and
observe an entangled superradiant state by measuring correlations of photons
collected from the diamond waveguide. This platform for tuning spectrally
stable color centers in nanophotonic waveguides and resonators constitutes an
important step towards a scalable quantum network.
