A group of applied physicists from Harvard University has unveiled a groundbreaking microwave-optic quantum transducer tailored exclusively for superconducting microwave qubit systems. This transducer aims to serve as a robust optical interface for quantum computers, seamlessly integrating into quantum networks. By effectively bridging the energy divide between microwaves and photons, it paves the way for the development of modular and distributed quantum computing networks. The research findings have been published in the prestigious journal Nature Physics. The transducer, a compact 2-millimeter device resembling a paperclip, is mounted on a 2-centimeter chip. It operates by interconnecting microwave and optical resonators, leveraging lithium niobate for efficient energy exchange.
