Using a superconducting qubit and a microscopic resonator, the team tracked a single phonon, or quantum of mechanical vibration, as it abruptly disappeared. This observation confirms that vibrating objects lose energy in discrete packets rather than a smooth fade. The experiment provides direct evidence of the jump-like nature of energy loss at the quantum level, a phenomenon predicted by quantum theory for over a century.Why it mattersQuantum theory suggests energy transitions occur in di
