A system that can distinguish phonons, the smallest units of sound, marks an important milestone in the development of more advanced quantum computers. Quantum computers might one day do things ...

Researchers at Stanford have developed a "quantum microphone" which can detect the smallest known units of sound -- packets of vibrational energy called phonons. The device could form the basis for ...

Researchers perform experiments that can add or subtract a single quantum of sound -- with surprising results when applied to noisy sound fields. Researchers perform experiments that can add or ...

For the first time, scientists can count individual phonons — the smallest units of sound — without destroying them. According to quantum mechanics, the vibrations that make up a sound wave are ...
