Sound waves do double duty, carrying and protecting quantum information

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a promising new way to protect fragile quantum information using nothing but mechanical vibrations-essentially extremely small sound waves. The breakthrough, which comes from the lab of Marko Lonar, Tiantsai Lin Professor of Electrical Engineering, paves a path toward compact, sound-based quantum networks on chips, as well as hybrid quantum systems that combine many different types of q...
