Stanford team observes first real-time quantum jump in sound

Researchers use superconducting qubit to detect phonon transitions without disturbing quantum state

1 Sep 17 2:00 PM · 6d ago · 6 articles · 1 post · 3 sources · development 1 of 1

Co-first authors Takuma Makihara and Erik Szakiel developed a method integrating a microscopic mechanical resonator with a superconducting qubit that could monitor the resonator's vibrations for two milliseconds without degrading either system. The qubit repeatedly checked whether the phonon remained at energy level 1 or had jumped to 0.

“We had to continually develop new processes to make this extremely long-lived, vibrating object and then integrate it with the qubit, without ruining either subsystem.”
