Complete Bell Measurement Based on the Quantum Teleportation
Pan Jian-wei · Acta Sinica Quantum Optica · 2009
To completely distinguish the four Bell States is the key of Quantum teleportation.Now by insing linear optics methods,we can not perform complete Bell measurement.Based on the method of two photon quantum teleportation which uses Mach-Zehnder interferometer,we propose a scheme which can completely make the Bell measurement in the quantum teleportation experiment in upper dimension space.Through the introduction of the reference of beam we can stabilize the interferometer′s phase automatically.The scheme is used in the 16km free space quantum teleportation experiment.
