Mathematical breakthrough sets out rules for more effective teleportation
January 16, 2013 For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of ‘entanglement’ may hold the key to eventual teleportation of quantum information.
Now, for the first time, researchers have worked out how entanglement could be ‘recycled’ to increase the efficiency of these connections. Published in the journal Physical Review Letters, the result could conceivably take us a step closer to sci-fi style teleportation in the future, although this research is purely theoretical in nature. The team have also devised a generalised form of teleportation, which allows for a wide variety of potential applications in quantum physics. Once considered impossible, in 1993 a team of scientists calculated that teleportation could work in principle using quantum laws. Quantum teleportation harnesses the ‘entanglement’ law to transmit particle-sized bites of information across potentially vast distances in an instant.
