MIT demonstrates room-temperature correlated microwave signals

MIT researchers reported a small electronic device that generates pairs of highly correlated microwave signals at room temperature, avoiding the cryogenic equipment normally used for comparable superconducting circuits. A magnetic film inside a microwave resonator creates hybrid magnon-photon waves that split an incoming signal into two correlated outputs at distinct frequencies. The team encoded a small image in one output and decoded it with its partner signal. The work appears in Nature Electronics.
