Realization of Bipartite Positive-Operator-Value Measurements of Two-Photon Polarization States
Lin Qing · Communications in Theoretical Physics · 2009
In this letter, we propose a scheme of a special quantum optical Fredkin gate assisted by optical manipulations and postselection from the coincidence measurements, and then modify it with cross-Kerr nonlinearities to be suitable for the realization of all possible positive operator-valued measurements of bipartite polarization states. This scheme is feasible in the lab with the current experimental technology.
