Microwave to optical state transfer with a cavity electro-opto-mechanical system

ORAL

Abstract

Quantum-coherent conversion between gigahertz-frequency ``microwave light'' and terahertz-frequency ``optical light'' would combine the processing power and scalability of superconducting qubits with the low-loss and long-distance distribution of optical fibers. Here we use an electro-opto-mechanical device to reversibly convert classical signals between microwave and optical light with an efficiency of ten percent. The frequency conversion is coherent and occurs over a 10 kHz bandwidth. This new type of converter opens new possibilities for generating and distributing entanglement, and is potentially capable of quantum-coherent frequency conversion.
