Microwave to optical transduction via engineered dissipation

Quantum transduction, coherent conversion of quantum information between disparate systems, is an essential element in quantum technology. One crucial application of quantum transduction is interconnection of a hybrid quantum network consisting of microwave-frequency quantum processors and optical-frequency quantum communication links. Microwave to optical conversion has been proposed and realized in various atomic platforms using coherent interactions. Here we present a quantum transduction scheme between microwave and optical frequencies via engineering suitable interactions with dissipative atomic levels. With atomic relaxation as the resource, the proposed quantum transduction process is completed autonomously by dissipation and is immune from noises at the receiver port. We consider protocols for both microwave-to-optical and optical-to-microwave directional transduction. Finally, we compare the performance of the proposed dissipation-based transduction protocols with other transduction schemes.
