Phonons demonstrate quantum superposition in groundbreaking experiment.

TL;DR
Scientists have successfully placed a phonon, a particle of sound, into superposition, allowing it to exist in two places at once. This achievement paves the way for the use of phonons in quantum computers, which rely on the principles of quantum physics to perform calculations. This feat is similar to what has been observed in electrons and photons, which are quanta of matter and light, respectively.
