Photon-mediated coupling between distant matter qubits may enable secure communication Panier Bike Seats over long distances, the implementation of distributed quantum computing schemes, and the exploration of new regimes of many-body quantum dynamics.Solid-state quantum emitters coupled to nanophotonic devices represent a promising approach towards these goals, as they combine strong light-matter interaction and high photon collection efficiencies.However, nanostructured environments introduce mismatch and diffusion in optical transition frequencies of emitters, making reliable photon-mediated entanglement generation infeasible.Here we address this long-standing Electric Knife Sharpener Parts challenge by employing silicon-vacancy color centers embedded in electromechanically deflectable nanophotonic waveguides.

This electromechanical strain control enables control and stabilization of optical resonance between two silicon-vacancy centers on the hour timescale.Using this platform, we observe the signature of an entangled, superradiant state arising from quantum interference between two spatially separated emitters in a waveguide.This demonstration and the developed platform constitute a crucial step towards a scalable quantum network with solid-state quantum emitters.
