Artificial atom probes sound’s quantum side

Sound is taking on some of light’s leading role in the quantum realm. Scientists have designed an artificial atom to emit sound that is divided into quantum particles. These quantum particles are the weakest sound that can be detected. Because sound travels at roughly a hundred-thousandth the speed of light, sound’s much slower-moving quantum particles should be easier to manipulate, giving scientists more control over the quantum world, the researchers argue September 11 in Science.
