思科系统公司($CSCO)上周公开的"通用量子交换机"明确指出,量子计算扩展的核心不在于单个设备的性能,而在于"网络"。这意味着量子计算机不再停留在孤立的实验设备阶段,而是正在向相互连接的"量子网络"演变。 当前业界期待的分子模拟、新材料发现、投资组合优化、大规模日程计算等高难度问题,需要10万到100万个逻辑量子比特才能解决。然而,根据主要路线图,即便是到2030年,现实情况也只能达到数千个,最多也只是数万个初期的水平。由于这一差距,业界正将方向转向"分布式量子计算",即连接多个小型处理器,使其像单一系统一样运行,而不是依赖一台超大型量子计算机。 为何需要量子网络 传统计算机网络仅需交换计算结果,但量子领域则不同。多个设备若要像一个集成系统一样运行,就必须在保持"纠缠"状态的同时传递量子态本身。在这个过程中,能够在不破坏光子量子特性的情况下改变路径的交换机是必不可少的。 思科的通用量子交换机正是针对这一角色而设计的研究设备。它旨在通过常温下普通通信光纤传输纠缠光子,并在保留量子信息的同时处理多种编码方式。特别是,与普通光交换机不同,其特点是使用内部"量子态转换器"以避免破坏量子态。 此外,它支持偏振、时间仓、频率、路径等主要量子编码方式,并能够相互转换,从而使采用不同方式的量子系统也能在同一网络中连接。这为基于中性原子、超导和光子的设备在同一基础设施上共同运行开辟了可能性。 思科的目标是"量子互联网"的基础 思科此前曾公开过每秒可产生约2亿对纠缠光子的纠缠源芯片。加上此次的交换机以及与纠缠分发、交换、量子隐形传态相关的软件堆栈,业界评价其已初步构建了"发射器-网络架构-控制体系"的框架。 在与合作伙伴Qunnect于纽约大都市区进行的实验中,思科在数公里的区间内演示了超越现有实验室水平的纠缠交换速度。这被解读为一个信号,表明量子网络已不再只是理论,而是进入了与实际通信基础设施相结合的阶段。 从市场角度来看,重要的一点是量子计算的经济价值可能并非来自单个设备销售,而是来自"资源共享化"。如同当今企业按需使用云端的中央处理器(CPU)和图形处理器(GPU)一样,未来量子计算资源也很可能通过网络捆绑提供。 思科的优势所在 量子网络并非量子硬件企业的专属领域。它需要现有的光通信基础设施、互联网协议(IP)网络、控制软件以及安全体系共同配合。这正是思科的强项所在。 思科通过其孵化组织Outshift,正在开发涵盖量子芯片、交换机、编译器、编排、分布式纠错以及后量子密码集成的整体架构。此外,思科正与IBM Quantum、Atom Computing等采用不同量子方式的企业合作,积累在真实环境中连接设备的经验。 最关键的在于,常温运行以及对通信波段的支持,使其能够最大限度地利用现有光纤和光通信生态系统。这降低了对特殊基础设施(如单独的极低温链路)的依赖,从而降低了电信运营商和云服务提供商的使用门槛。 IT业界现在应做的准备 短期内,大部分企业不太可能在明年就引入量子交换机。然而,未来3到5年内,选择何种网络架构将极大影响其对量子转型的应对能力。 专家建议,首先应将量子计算视为"多供应商网络服务",而非单一供应商的技术。这意味着在制定数据中心和广域网战略时,需考虑到大型云服务商、专业量子云以及本地设备相互连接的结构。 此外,在安全方面,有必要同时考虑后量子密码的过渡以及量子网络的应对。量子计算机可能威胁现有密码体系,但反之,量子网络也可能提供更强的安全模型。最终,如何设计经典网络与量子链路共存的混合结构,预计将成为核心课题。 思科此次的发布表明,量子计算正在超越"物理实验"阶段,转变为企业IT应纳入中长期路线图的基础设施议题。量子时代的胜负,不仅取决于谁先获得更多的量子比特,也越来越可能取决于谁能最高效地连接这些资源。 TP AI 注意事项 本文基于TokenPost.ai语言模型进行摘要。正文主要内容可能存在遗漏或与事实不符之处。
