Scientists at Argonne National Laboratory and the University of Chicago have successfully demonstrated a series of benchmark coherent gate operations in hybrid magnonics. Their discovery allows real-time control of information transfer between microwave photons and magnons and  could result in a new generation of classical electronic and quantum signal devices.

The research points to a new direction for electromagnonics. Most importantly, the demonstrated mechanism not only works in the classical electronics régime, but can also be readily applied for manipulating magnonic states in the quantum régime. This opens opportunities for electromagnonics-based signal processing in quantum computing, communications, and sensing.

This researchers describe their work in "Coherent Gate Operations in Hybrid Magnonics," published in Physical Review Letters.
