对声子数开展重复量子非破坏性测量,这类不连续跃迁, Amir H. Safavi-Naeini IssueVolume: 2026-09-17 Abstract: Quantum mechanics predicts that a vibrating objects energy comes in discrete packets,最新IF:63.714 官方网址: https://www.sciencemag.org/ , one coupling to the resonators energy rather than its displacement. We use a superconducting qubit dispersively coupled to a nanomechanical resonator to perform repeated quantum nondemolition measurements of the phonon number. An aligned transfer-print technique integrating the qubit and resonator yields a mechanical lifetime of T1=2.1 milliseconds and a dispersive shift of 2/2=328 kilohertz per phonon. We heralded single-phonon states with 85% fidelity and observed quantum jumps between the resonators first excited state and ground state. These discontinuous transitions are a striking manifestation of quantum mechanics in a massive, Kaveh Pezeshki, David I. Schuster。
