Mathematicians Make Teleportation Possible (Again)

If you are going to use 'entanglement' to teleport quantum information on a practical scale, it needs to be worked out how entanglement could be 'recycled' to increase the efficiency of these connections. Writing in  Physical Review Letters , a group has done just that - mathematically. They have also devised a generalized form of teleportation, which allows for a wide variety of potential applications in quantum physics. read more
