600. 硅基11位原子量子处理器
from 知为谁 · host 知为谁
这项研究介绍了一种在同位素纯化硅中构建的11位原子量子处理器，该系统由两个通过电子交换相互作用相连的磷原子核自旋寄存器组成。研究团队利用精准原子放置技术实现了高保真度的单比特与多比特操作，其逻辑门精度普遍超过了99%。通过建立这种相干连接，科研人员成功演示了处理器内部所有数据比特间的全连通性，并生成了多达八个核自旋的纠缠态。这种架构克服了以往半导体量子器件在比特扩展与操控稳定性方面的挑战，为实现容错量子计算提供了重要的技术路径。该成果标志着硅基量子平台在模块化扩展和高性能逻辑运算方面取得了重大突破。内容来源：https://www.nature.com/articles/s41586-025-09827-w
