Researchers at Harvard have demonstrated a way to protect quantum information using microscopic sound waves. By continuously surrounding a diamond-based qubit with mechanical vibrations, they extended its coherence time by roughly threefold. The same phonons could eventually both transmit and protect quantum information, opening the door to compact sound-based quantum networks on chips.
