牛津大学研究人员成功利用混合量子计算机重现了阿哈罗诺夫-博姆效应，这是一种量子现象，其中带电粒子受到磁场影响而无需通过磁场本身。1 该效应最初由雅基尔·阿哈罗诺夫和大卫·玻姆在1959年预言。1 这项研究由塞巴斯蒂安·桑纳博士领导，始于2022年，已发表在《自然物理学》期刊上。1
实验中，研究人员将磁通量编码到动态规范场而非固定背景条件中，通过结合量子比特和量子振荡器进行模拟。1 研究演示了两条量子路径的破坏性干涉如何导致隧穿完全被抑制，从而阻止粒子的运动。1 这一成果展示了混合量子计算机在研究物质与场相互作用中的潜力。1 马里兰大学诺伯特·林克教授团队同期独立开展了相关研究工作。1
Researchers at Oxford University have successfully recreated the Aharonov-Bohm effect, a counterintuitive quantum phenomenon in which charged particles are influenced by magnetic fields without directly passing through them.1 The team used a hybrid quantum computer combining quantum bits and quantum oscillators to simulate how encoded magnetic flux can completely suppress particle movement through quantum interference.1 The findings, published in Nature Physics, demonstrate the potential of hybrid quantum computers for studying interactions between matter and fields.1
The Aharonov-Bohm effect was theoretically predicted in 1959 by Yakir Aharonov and David Bohm.1 In the Oxford experiment, magnetic flux was encoded into a dynamic gauge field rather than a fixed background condition, and the researchers observed destructive interference between two quantum paths that led to complete suppression of tunneling.1 The project, led by Dr. Sebastian Zanner, began in 2022.1 Independently, a research team at the University of Maryland led by Professor Norbert Link conducted related work during the same period.1
