Reducing Added Noise in a Microwave-Mechanical-Optical Converter

Viewed as resources for quantum information processing, microwave and optical fields offer complementary strengths. The ability to transduce quantum information between microwave and optical frequencies is an essential technology in realizing an extended quantum network. This talk describes the design and characterization of a device that couples one mode of a micromechanical oscillator to a resonant microwave circuit and a high-finesse optical cavity, thereby realizing a mechanically mediated electro-optic converter.
