Enhancing Interferometry Using Weak Value Amplification with Real Weak Values

Author(s): Jing-Hui Huang, Kyle M. Jordan, Adetunmise C. Dada, Xiang-Yun Hu, and Jeff. S. Lundeen We introduce an ultrasensitive interferometric protocol that combines weak value amplification (WVA) with traditional interferometry. This protocol $\mathrm{WVA}+\text{interferometry}$ uses weak value amplification of the relative delay between two paths to enhance interferometric sensitivity. As an… [Phys. Rev.
