Non-local quantum metrology with entangled photons and geometric phase
Anton N. Vetlugin, Ruixiang Guo, Cesare Soci, Nikolay I. Zheludev · 2023
We demonstrate a new protocol of non-local quantum metrology in which the sample displacement is measured with entangled photon pairs by manipulating the geometric phase of the photon that has never interacted with the sample.
