Sound waves let quantum systems ‘talk’ to one another

Phys.org   February 18, 2019
Transferring information between different types of technology, such as quantum memories and quantum processors has been a persistent challenge. To couple the sound waves with the spins of electrons in the material an international team of researchers (University of Chicago, UC Santa Barbara, Argonne National Laboratory, Japan) built a system with curved electrodes to concentrate the sound waves, like using a magnifying lens to focus a point of light. Using the synchrotron they observed inside the material as the sound waves moved through it. The research reveals the importance of shear strain for future device engineering and enhanced spin–mechanical coupling…read more. TECHNICAL ARTICLE
