摘要

我们提出了一种干涉测量方案，即每个光子返回未知相位二进制扩展的一个比特。它建立了一种在任意不确定性条件下估算相位值的方法。这种策略是全局性的，因为它不需要任何先验信息，而且它能独立于输出统计量实现海森堡约束。我们对这一架构进行了模拟和描述。

Interferometric binary phase estimations

We propose an interferometric scheme where each photon returns one bit of the binary expansion of an unknown phase. It sets up a method for estimating the phase value at arbitrary uncertainty. This strategy is global, since it requires no prior information, and it achieves the Heisenberg bound independently of the output statistics. We provide simulations and a characterization of this architecture.
