  The implementation of quantum networks involving quantum memories and
photonic channels without the need for cryogenics would be a major
technological breakthrough. Nitrogen-vacancy centers have excellent spin
properties even at room temperature, but phonon-induced broadening makes it
challenging to interface these spins with photons at non-cryogenic
temperatures. Inspired by recent progress in achieving ultra-high mechanical
quality factors, we propose that this challenge can be overcome by
spin-opto-mechanical transduction. We quantify the coherence of the interface
by calculating the indistinguishability of the emitted photons and describe
promising paths towards experimental implementation.
