Quantum Microphone Counts Sound “Particles”

Stanford physicists have developed a “quantum microphone” that can measure individual particles of sound, called phonons. The device could lead to smaller, efficient quantum computers that operate by manipulating sound rather than light. “We expect this …Read more

Physicists count sound particles with quantum microphone

Artists impression of an array of nanomechanical resonators designed to generate and trap sound particles or phonons The mechanical motions of the trapped phonons are sensed by a qubit detector which shifts its frequency depending on the number of
