Summary

Story summary

Stanford researchers observed quantum jumps of sound in real time with a chip-scale resonator coupled to a superconducting qubit.
The resonator rings 2.1 ms while each qubit readout lasts about 12 µs, far faster than decay.
Jump events average 645 µs, and each measurement carries a 1.3% chance of removing the phonon.
Detecting phonon jumps could flag errors in quantum computers and enable ultra-sensitive protein sensing.
