这是量子计算技术向传感技术的巧妙转化，让传感器在量子噪声干扰下也能捕捉微弱信号。团队表示， 这种测量仍处于实验室阶段，但为未来量子传感技术提供了新框架，既可与现有方法互补，也可能催生 全新的应用领域。正如原子钟曾彻底改变导航与电信，极端灵敏的量子增强传感器也可能开辟全新的产 业。 （文章来源：科技日报） 团队用钟表作比喻来解释他们的发现：只有时针的钟表能粗略读出分钟，但具体时刻不准；只有分针的 钟表能精确读分钟，却无法判断小时。同理，他们通过牺牲部分全局信息，将量子测量的精度集中在微 小变化上，实现了对粒子位置和动量的同时高精度测量。这种测量理念就是"模运算"。 团队利用先前为量子纠错计算机开发的技术，首次在实验中验证了这一策略。他们将囚禁离子制备 为"网格态"，即量子计算中用于纠错的特殊量子态，通过测量离子的微小振动，实现位置和动量的联合 测量，精度超过传统经典传感器的"标准量子极限"。 澳大利亚和英国科学家团队提出一种新方法，可以同时精确测量粒子的位置和动量，重塑了量子不确定 性，为未来超精密传感技术奠定了基础。新方法的应用领域包括导航、医学和天文学。相关研究成果发 表在最新一期《科学进展》杂志上。 海森 ...
