Big Home	The dream of teleportation is to be able to travel by simply reappearing at some distant location. It might appear that one could scan the object and send the information so that the object can be reconstructed at the destination. Yet, fundamental laws like the Heisenberg uncertainty relation do not allow one to measure any object to arbitrary precision. Charles H. Bennett and his co-workers have suggested that it is possible to transfer even quantum states, provided one does not get any information about the state. This becomes possible by utilizing entanglement, one of the essential features of quantum mechanics. Here we present the first experimental verification of quantum teleportation. By producing pairs of entangled photons by the process of parametric down-conversion and using two-photon interferometry for analysing the entanglement, we could transfer a quantum property (in our case the polarization state) from one photon to another.
