A Scheme of Teleportation of the Phase
In a recent paper a scheme with two EPR states was proposed, being a sort of entanglement swapping for teleportation of the phase. In the present paper we shall show that the scheme is based on the well-known quantum transformations: two-particle spatial correlation of entangled photons, teleportation, and two-photon interference of independent particles. The scheme does not call for additional classical channels that admits signaling. The signaling suggested is consistent with the peaceful coexistence.
