Stanford physicists have developed a “quantum microphone” so sensitive that it can measure individual particles of sound, called phonons.
The device, which is detailed July 24 in the journal Nature, could eventually lead to smaller, more efficient quantum computers that operate by manipulating sound rather than light.
“We expect this device to allow new types of quantum sensors, transducers and storage devices for future quantum machines,” said study leader Amir Safavi-Naeini
