这项突破并非来自新发现的材料，而是源于制造工艺的革新。传统方法采用"直拉法"，即将原料在超过 2000摄氏度的高温熔炉中熔化，再缓慢冷却结晶，随后通过化学蚀刻"雕刻"出所需器件。而现在团队改 用了一种名为分子束外延的技术，逐层喷涂原子，像3D打印一样精准构建晶体结构。 量子光学领域先驱、西班牙巴塞罗那光子科学研究所教授于格·德·里德马滕未参与此项研究，他评论 称，该项工作极具创新性，为未来规模化生产可联网量子比特开辟了一条可行路径。 下一步，团队将验证延长的相干时间是否真能支撑长距离量子通信，他们已计划模拟跨城市通信场景。 美国芝加哥大学普利兹克分子工程学院团队突破了量子通信瓶颈，从理论上将量子计算机之间的连接距 离大幅扩展至2000公里。按照这一进展，原本无法"对话"的芝加哥大学量子计算机，现在甚至能与远在 犹他州盐湖城郊外的设备建立联系。团队表示，这意味着构建全球规模量子互联网的技术首次真正"触 手可及"。这一研究成果发表在最新一期《自然·通讯》上。 量子计算机以其强大的计算能力和惊人的运算速度著称，但长期以来，它们难以实现长距离互联。此 前，两台量子计算机通过光纤连接的最远距离仅有几公里，这意味着即便铺 ...

早在2020年2月，美国能源部阿贡国家实验室与芝加哥大学的科学家就宣布，他们在位于芝加哥郊区的 一个52英里（83.7公里）长的量子环网络中实现了量子纠缠——即一对微小粒子的行为相互关联，使其 状态完全一致。 如果你不是熟悉量子力学的科学家，你可能想知道这是怎么回事——为什么物质和能量在现实的最小尺 度上的这些行为与我们身边看到的世界截然不同。 但是研究人员的这项成就，可能成为未来几十年开发新一代、更强大互联网的重要一步。与当今网络使 用的只能表示0或1的比特不同，未来的量子互联网将利用量子信息中的量子比特，它可以呈现无限多种 值。（量子比特是量子计算机的信息单位，相当于经典计算机中的比特）。 这将使量子互联网获得更多的带宽，从而能够连接超强量子计算机及其他设备，运行大规模的应用程序 ——这些在现有互联网条件下是根本无法实现的。 路易斯安那州立大学巴吞鲁日分校的研究员苏米特·卡特里(Sumeet Khatri)在一封邮件中表示："理解量 子互联网概念最简单的方法就是通过理解量子隐形传态的概念。"他与同事们撰写了一篇关于天基量子 互联网可行性的论文，正如《技术评论(Technology Review)》这篇文章 ...
