Physicists split bits of sound using quantum mechanics
Quantum weirdness applies to sound as well as to light and atomic particles

Sound waves (illustrated) come in tiny quantum chunks called phonons. New experiments show how phonons exhibit the same quantum weirdness shared by photons and subatomic particles.
