斯坦福大学研究团队在量子物理领域取得突破性进展，首次直接观察到单个声子从一个能量态突然跳跃到另一个能量态的现象1。这项由阿米尔·萨法维-纳伊尼领导的研究成果已发表在《科学》杂志2026年393卷第6817期1。
研究人员采用微型机械谐振器与超导量子比特耦合的创新方法，解决了在不扰动量子态情况下进行测量的难题1。所使用的机械谐振器能够维持振动达2毫秒，这一性能相对来说相当于普通音叉能响数小时1。这项技术突破为量子计算、量子误差纠正和高灵敏度生物传感器的发展开辟了新途径1。该研究得到了亚马逊网络服务公司、美国空军科学研究办公室、海军研究办公室和国家科学基金会等多个机构的资金支持1。
Researchers at Stanford University have achieved the first direct observation of quantum jumps in sound, capturing individual phonons transitioning abruptly from one energy state to another.1 Led by Amir Safavi-Naini, the team developed a technique coupling a miniature mechanical resonator with a superconducting qubit, enabling measurements without disturbing the quantum state—a challenge that has long hindered quantum research.1
The mechanical resonator can vibrate for approximately 2 milliseconds, a feat comparable to a conventional tuning fork sustaining its resonance for several hours.1 This breakthrough, published in Science in 2026 (Volume 393, Issue 6817, page 1217, DOI: 10.1126/science.aeh7535), opens new pathways for advancing quantum computing, quantum error correction, and ultra-sensitive biological sensing applications such as protein detection.1 The research was supported by funding from Amazon Web Services, the U.S. Air Force Office of Scientific Research, the Office of Naval Research, and the National Science Foundation.1
