Mathematical findings took us closer to the Teleportation phenomenon

(Credit: © vlights / Fotolia)Mathematical finding helped scientists to get closer to the practical teleportation i.e. moving somewhere without traveling.

This research has been published in the journal Physical Review Letters.

For more than a decade, researchers including theoretical physicists are of the opinion that there is a strong connection between the particles and for the past decade, scientists found that those strong connections as established in the quantum law of ‘entanglement’ could help us in the teleportation process.

Entanglement refers to the phenomenon of harmonization of two particles such as protons or electrons at a distance. Einstein famously spoke about the quantum entanglement as “spooky action at a distance.”

Researchers are of the opinion that this synchronization of two particles can be utilized giving double results at the same time i.e. quantum bits of information – qubits – can be utilized and this utilization can also help us in teleportation phenomenon.

“There is a close connection between teleportation and quantum computers, which are devices which exploit quantum mechanics to perform computations which would not be feasible on a classical computer,” said Sergii Strelchuck from Cambridge’s Department of Applied Mathematics and Theoretical Physics, who led the research with colleagues Jonathan Oppenheim of Cambridge and UCL and Michal Horodecki of the University of Gdansk.

“Building a quantum computer is one of the great challenges of modern physics, and it is hoped that the new teleportation protocol will lead to advances in this area.”

Previously two teleportation protocols were considered. One protocol was able to send only scrambled information requiring correction by the receiver and the other “port-based” teleportation that doesn’t need correction but needs an impractical amount of entanglement as entangled state would be disturbed by sending the data or objects.

In the recent research, scientists have proposed an optimal protocol for recycling the entangled state. They have also devised a protocol for simultaneous teleportation of multiple qubits.

“The first protocol consists of sequentially teleporting states, and the second teleports them in a bulk,” said Strelchuck.

“We have also found a generalised teleportation technique which we hope will find applications in areas such as quantum computation.”

Although, the protocols are theoretical, but they could help in moving further with teleportation studies.

“Entanglement can be thought of as the fuel, which powers teleportation. Our protocol is more fuel efficient, able to use entanglement thriftily while eliminating the need for error correction.” Strelchuck added.
