Clamped and sideband-resolved silicon optomechanical crystals
We present a new class of clamped OMCs realizing — for the first time — optomechanical interactions in the resolved-sideband regime required for quantum transduction. We observe a record zero-point optomechanical coupling rate of g0/(2π)≈0.50 MHz along with a sevenfold improvement in the single-photon cooperativity of clamped OMCs.

Optically heralded microwave photon addition
We implement and demonstrate a transducer device and use it to show that by detecting an optical photon we add a single photon to the microwave field. We achieve this by using a gigahertz nanomechanical resonance as an intermediary, and efficiently coupling it to optical and microwave channels through strong optomechanical and piezoelectric interactions.
