Harvard researchers use sound waves to shield quantum bits from noise

As of September 2026: Lead institution for the demonstration

Harvard researchers extended the memory of a diamond-based quantum bit roughly threefold by surrounding it with a continuous stream of microscopic sound waves. The technique, published in Nature Physics, could let phonons both carry and protect quantum information in compact networks built on chips.
