dsinc (319470) writes "Once considered impossible, in 1993 a team of scientists calculated that teleportation could work in principle using quantum laws. Quantum teleportation harnesses the âentanglementâ(TM) law to transmit particle-sized bites of information across potentially vast distances in an instant.
Entanglement involves a pair of quantum particles such as electrons or protons that are intrinsically bound together, retaining synchronisation between the two that holds whether the particles are next to each other or on opposing sides of a galaxy. Through this connection, quantum bits of information â" qubits â" can be relayed using only traditional forms of classical communication.
Previous teleportation protocols have fallen into one of two camps, those that could only send scrambled information requiring correction by the receiver or, more recently, âoeport-basedâ teleportation that doesnâ(TM)t require a correction, but needs an impractical amount of entanglement â" as each object sent would destroy the entangled state.
Now, physicists from Cambridge, University College London, and the University of Gdansk have developed a protocol to provide an optimal solution in which the entangled state is ârecycledâ(TM), so that the gateway between particles holds for the teleportation of multiple objects."
