Argonne National Laboratory and the University of Illinois Urbana-Champaign reported a laboratory demonstration coupling traveling spin waves in a magnetic material to a superconducting resonator. Argonne’s October 13 announcement describes a hybrid approach to one-way microwave signal control.

The experiment used a circuit on a yttrium iron garnet film. Researchers selected a substrate without rare-earth metals to reduce microwave losses at low temperatures. The result is a proof of concept for future on-chip quantum components, not a commercial quantum processor.
