The Innsbruck quantum teleportation experimental scheme can be modified to the unconditional one
Wang Xiang-bin
Abstract
We show that the Innsbruck quantum teleportation experiment(Bouwmeester D et al, Nature 390, 575(1997)) can be modified by using the polarized beam splitter. In this modified scheme, Bob does not have to do any meassurement and an unknown state from Victor can be verified to be teleported to Bob from Alice by the currently exisiting technology, i.e., by using the normal photon detectors which do not distinguish one photon and two photons.
