Iterative algorithm for reconstruction of entangled states
J. Rehacek, Z. Hradil, M. Jezek
Abstract
An iterative algorithm for the reconstruction of an unknown quantum state from the results of incompatible measurements is proposed. It consists of Expectation-Maximization step followed by a unitary transformation of the eigenbasis of the density matrix. The procedure has been applied to the reconstruction of the entangled pair of photons.
