[Caption] Einstein famously loathed the theory of quantum

entanglement, dismissing it as "spooky action at a

distance". But entanglement has since been proven to be a

very real feature of our universe, and one that has

extraordinary potential to advance all manner of

scientific endeavor.

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.

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 - qubits - 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, "port-based" teleportation that doesn't require

a correction, but needed an impractical amount of

entanglement - 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 'recycled', so that the gateway

between particles holds for the teleportation of multiple

objects.
