摘要

我们研究了挤压技术如何提高多相量子计量学的测量精度。虽然这些方法在单相估算中得到了深入研究和有效应用,但它们在多相情况下的应用还有待研究。我们通过研究多相情况下的量子增强机制填补了这一空白。我们的分析为实现量子克拉梅尔-拉奥约束的最佳条件提供了理论和数值见解,帮助我们理解量子增强多相挤压估计的潜力和机制。本文为量子计量学和传感技术的进步提供了可能性。

Squeezing-induced quantum-enhanced multiphase estimation

Squeezing-induced quantum-enhanced multiphase estimation
We investigate how squeezing techniques can improve the measurement precision in multiphase quantum metrology. While these methods are well studied and effectively used in single-phase estimations, their usage in multiphase situations has yet to be examined. We fill this gap by investigating the mechanism of quantum enhancement in the multiphase scenarios. Our analysis provides theoretical and numerical insights into the optimal condition for achieving the quantum Cramér-Rao bound, helping us understand the potential and mechanism for quantum-enhanced multiphase estimations with squeezing. In this paper, we open possibilities for advancements in quantum metrology and sensing technologies.
