Integrated optomechanical and superconducting quantum circuits

October 24, 2016 - 11:00am
Oskar Painter

I will present recent work at Caltech on the integration of optomechanical crystals for light and sound with electronic superconducting quantum circuits.  Utilizing the silicon-on-insulator (SOI) wafer platform, we have made key advances in the fabrication and integration of extremely low loss microwave phonon structures and low loss microwave superconducting resonators of high impedance.  These technical advancements offer several intriguing opportunities for quantum information processing and networking with phonons, photons, and electrons in an integrated, wafer-scale platform.  The focus of my talk will be on two examples of our efforts in this direction: (i) nonreciprocal photon transport and amplification arising from synthetic magnetic flux and reservoir engineering in an optomechanical crystal circuit, and (ii) waveguide-QED systems consisting of microwave-bandgap circuits with embedded transmon-like qubits.
