论文摘要
弱价值放大采用选择后来增强对少量感兴趣的参数的测量。放大是以降低成功概率为代价的,这阻碍了该技术作为实用计量学工具的实用性。遵循其他显示量子优势的量子技术,我们在成功概率中形式上了量子优势,并基于非线性集体汉密尔顿人的方案,该方案显示了成功概率的超扩张增长,同时表现出弱价值的广泛增长。我们提出了我们计划的实验实施。
Weak-value amplification employs postselection to enhance the measurement of small parameters of interest. The amplification comes at the expense of reduced success probability, hindering the utility of this technique as a tool for practical metrology. Following other quantum technologies that display a quantum advantage, we formalize a quantum advantage in the success probability and present a scheme based on non-linear collective Hamiltonians that shows a super-extensive growth in success probability while simultaneously displaying an extensive growth in the weak value. We propose an experimental implementation of our scheme.
