这一成果的意义不仅在于速度的飞跃,更在于它展示了量子技术在传感、系统识别乃至机器学习等领域 的潜在应用价值。 一项由丹麦、美国、加拿大和韩国联合团队开展的国际合作研究,首次通过实验证明了量子技术在特定 任务中远超经典方法的能力,完成任务时间从2000万年缩短到15分钟,真正实现了"量子优势"。该成果 发表在新一期的《科学报告》上。 该研究为量子计量和量子传感开辟了新路径,也表明量子优势不再是纸上谈兵,它已经在实验室的光路 中悄然发生。(记者张梦然) 实验采用的是标准的光学元件和通信波段的光。团队制备了两束相互纠缠的压缩光,其中一束用于探测 目标系统,另一束作为参考。通过对这两束光进行联合测量,他们能够一次性提取出更多有效信息,显 著减少了测量模糊性。 结果令人震惊:原本需要约2000万年才能完成的系统表征任务,使用纠缠光仅用15分钟就完成了。这种 效率提升并非源于设备更精密,而是测量方式本身的量子优势。因为团队并没有依赖理想化的无损环 境,而是在一个现实、有损耗的系统中实现了这一突破。 研究的核心问题源于一个普遍存在的挑战:如何高效地了解一个复杂且充满噪声的物理系统。在传统方 法中,科学家需要反复测量系统,通 ...
