The quest for mechanical oscillators with ultralow dissipation is motivated by classical and quantum sensing and technology, as well as precision measurements.

The project proposes a new generation of strain-engineered crystalline and superconducting mechanical oscillators, whose Q-factors are predicted to exceed 100 billion in up to 2 dimensions.

Secondly, the project will explore a fundamentally new method for measurement and manipulation of microwave fields with optical fields – the nascent field of circuit Cavity-Electro-Optics (cCEO). Taken together, the study can open cCEO to usher in a new era of mechanical coherence within classical and quantum domains.
