Researchers Observe First Real-Time Quantum Jump in Sound
Stanford physicists recorded the first real‑time quantum jumps of sound by monitoring individual phonons in a microscopic mechanical resonator coupled to a superconducting qubit. The resonator, fabricated with chip‑making techniques, vibrated for two milliseconds, allowing repeated measurements that captured discrete energy transitions from one phonon state to zero. The experiment demonstrates quantum behavior in sound, a prerequisite for quantum computing error correction and ultra‑sensitive sensing, such as protein detection in cells. The findings were published in Science. [...]
