The century-old prediction, first demonstrated with trapped ions in 1986 and with photons in 2007, had never been captured for units of sound until now.\n\nThe team, led by physicist Amir Safavi-Naeini with co-first authors Takuma Makihara and Erik Szakiel, built a microscopic mechanical resonator using chip-fabrication techniques and paired it with a superconducting qubit as a detector. The resonator vibrates for about two milliseconds — a comparatively enormous \"ringdown time\" that let the qubit take hundreds of measurements per run, repeatedly checking whether the vibrational energy sat at state 1 or 0 to pinpoint the exact moment of transition.\n\nThe result, published in Science, opens paths toward quantum error correction for quantum computers, ultra-sensitive biological sensors capable of detecting individual proteins in cells, and finer control over sound-based technology in everyday devices. \"This shows we can have incredibly fine-tuned control of sound,\" the researchers said, \"which might mean that devices that use sound as a fundamental technology can get much better.\""}}
