Low-noise transducers can bridge the gap between microwave and optical qubits

https://phys.org/news/2025-03-noise-transducers-bridge-gap-microwave.html 

"microwave photons as qubits: ease of control/ scalable fabrication, cooled to -459.6°F to keep background noise low... room temperature transmitting via optical cables requires conversion to higher-energy optical photons using on-chip silicon beam transducer vibrating at 5 GHz coupled to microwave resonator... electrostatic actuation converts to mechanical vibration, which with laser converts to optical photon... conversion 100X faster with same low noise... internet of superconducting quantum computers"
