科学家研发出新型量子互连平台,量子互联网将加速构建
Sou Hu Cai Jing· 2026-01-01 09:51
近日,位于美国印第安纳州的普渡大学实验室里,研究人员宣布了一项关键突破:他们开发出一种新型 量子互连平台,成功将多个独立的量子处理器连接在一起,传输效率比现有技术高出百倍。 这项技术的意义不亚于发明了量子世界的"光纤",为构建全球量子互联网迈出了至关重要的一步。 构建量子互联网的首要障碍是量子态的脆弱性。每个量子比特都像是一座玻璃城堡里的勇士——威力强 大但极度敏感,任何微小的干扰都会导致"量子退相干",使这些量子比特失去魔力。 科学家们面临着一个看似无解的困境:既要让量子比特相互交流,又要保护它们不受外界干扰。 此前量子计算机的规模难以突破的一个重要原因正是这种连接困境。即使是现在最先进的量子计算机, 其内部的量子比特数量也不过几百个。要将这些脆弱的量子比特连接成网络,难度不亚于用蜘蛛丝编织 一张横跨太平洋的网。 令人惊叹的是,整个转换过程的保真度高达99.7%,意味着信息在传递过程中几乎没有任何失真。 这项技术的神奇之处还在于它的可扩展性。现有的量子连接技术通常只能实现点对点的链接,而普渡大 学的新平台能够同时连接多个量子节点,形成一个真正的量子网络。 这就像是从只能两人通话的老式电话,进化到了可以多方视 ...
