Superconducting Electro-Mechanics

The nonlinear I-V characteristics of superconducting (SC) Josephson Junctions (JJs) have recently been employed to create macroscopic electronic quantum bits (qubits). By combining JJ-based qubits with superconducting microwave resonators and co-planar waveguides, researchers have developed what looks to be a very promising technology for fault-tolerant quantum computation. We are developing a quantum optical interface with SC quantum circuits based upon mechanical transducers.
