A real-time quantum jump of sound caught in a chip resonator

Stanford’s Humanities page on 17 September says Safavi-Naeini’s group watched a mechanical resonator drop from phonon energy 1 to 0, with a qubit taking hundreds of readings inside two milliseconds. The university says the paper is in Science. Live Science and Science News homepages fetched this slot had no separate write-up of that paper.

From 1 to 0

The university page says the run caught the resonator leaving energy 1 for energy 0. Safavi-Naeini, in applied physics, said oscillating hardware can show quantum traits, useful in computing and sensing work. The feature is dated 17 September 2026 and points to Science.

A qubit as the ear

The page names Takuma Makihara and Erik Szakiel as joint first authors. They coupled the resonator to a superconducting qubit that reads the motion without wiping the state on first touch. Hundreds of samples landed inside two milliseconds. Chip-shop methods made the resonator, the university says. Those figures and proper names sit in that same-day article and attach to this event only.[1]

What a phonon is here

Stanford treats a phonon as many atoms moving together, distinct from one photon. A struck bell seems to fade smoothly to the ear; the university says the resonator instead drops in discrete energy steps. Earlier experiments had hints of those steps; this write-up says single phonons were seen jumping live. Those figures and proper names sit in that same-day article and attach to this event only.[1]
