A new bridge for quantum networks: Physicists convert microwaves to light using 2D magnets

Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces that could one day link quantum computers through optical networks. The research, titled "Microwave-to-optical transduction using magnon–exciton coupling," was led by the Laboratory for Nano and Micro Photonics (LaNMP) at CCNY, headed by physics professor Vinod M. Menon. It appears in the journal Nature Materials.
