摘要
In this article,we introduce a framework for entanglement quantification of photon pairs represented by two-qubit Werner states.The measurement scheme is based on the symmetric informationally complete POVM.To make the framework realistic,we impose the Poisson noise on the measured two-photon coincidences.For various settings,numerical simulations were performed to evaluate the efficiency of the framework.
