UNSW研究人员使硅中的远方原子核能够通过电子进行通信,这是向可缩放量子计算机迈出的关键一步。 UNSW researchers enabled distant atomic nuclei in silicon to communicate via electrons, a key step toward scalable quantum computers.

新南威尔士大学的研究人员通过使硅芯中的原子核能够使用电子进行远距离通信,从而推进了量子计算,这一突破可以使可扩展的、实用的量子计算机成为可能。 Researchers at the University of New South Wales have advanced quantum computing by enabling atomic nuclei in silicon chips to communicate over distances using electrons, a breakthrough that could enable scalable, practical quantum computers. 该小组利用在空间散布的电子在不破坏核心稳定性的情况下调解相互作用,在以大约20纳米(大约是人类头发宽度的1千米)隔开的磷原子核之间实现了纠缠。 The team achieved entanglement between phosphorus atom nuclei separated by about 20 nanometers—roughly one-thousandth the width of a human hair—by using electrons that spread out in space to mediate interactions without disrupting the nuclei’s stability. 这一方法保留长效量子信息储存,同时允许有控制的远距离通信,克服以前要求核心极接近的限制。 This method preserves long-lasting quantum information storage while allowing controlled communication across distances, overcoming previous limitations that required nuclei to be extremely close. 这一方法与现有的硅芯片制造兼容,利用久已确立的半导体技术。 The approach is compatible with existing silicon chip manufacturing, leveraging well-established semiconductor technology. 2025年9月18日发表于Science 2025年9月18日的《科学》中。 这项工作以新南威尔士大学多年的研究为基础,是朝向大规模低度量子处理器迈出的一大步。 Published in Science on September 18, 2025, the work builds on years of research at UNSW and represents a major step toward large-scale, low-error quantum processors.
