Our Photon Router: Superconducting Quantum Transduction
We have recently demonstrated a photon router that could plug into quantum networks to create robust optical interfaces for noise-sensitive microwave quantum computers.
Our transducer device bridges the large energy gap between microwave and optical photons, allowing optical signals -- sent from miles away -- to control microwave qubits. It is the first device to achieve control of a superconducting qubit using light alone.
As the paper's first author, graduate student Hana Warner said, “optical photons are one of the best ways you can do that, because they’re very good carriers of information, with low loss, and high bandwidth.”
