Nonlocal photon number states for quantum metrology
Author(s): Markus Aspelmeyer; Philip Walther; Thomas Jennewein; Anton Zeilinger

Paper Abstract

Quantum metrology utilizes nonclassical states (of light) to outperform the accuracy limits of its classical counterpart. We demonstrate the relevance of photon number Fock states and polarization entanglement for the experimental realization of interferometric quantum metrology applications.
