QUANTUM TELEPORTER

Quantum Teleportation has been successful on smaller objects according to a Study. “We were able to perform a quantum teleportation experiment for the first time ever outside a university laboratory,” said Rupert Ursin, a researcher at the Institute for Experimental Physics at the University of Vienna in Austria. In quantum Teleportation it is the quantum states of the objects that are destroyed and recreated, and not the objects themselves. Therefore, quantum Teleportation cannot teleport animate or inanimate matter in its physical entirety. The device thus creates a replica of an original thing at a new position and the original thing ceased to exist once the replicas were created.
Quantum teleportation is a process by which a quantum information can be transmitted exactly from one location to another, without the  information being transmitted through the intervening space. It is useful for quantum information processing, however it does not immediately transmit classical information, and therefore cannot be used for communication at a speed faster than light. Quantum teleportation is different from teleportation, it does not transport the system itself, and does not concern rearranging particles to copy the form of an object.

Work in 1998 verified the initial results, and in August 2004 increased the distance of teleportation to 600 meters using optical fiber. The longest distance yet claimed to be achieved for quantum teleportation is 143 km (89 mi) in May 2012 between the two Canary Islands of La Palma and Tenerife off the Atlantic coast of north Africa. In April 2011, experimenters reported that they had demonstrated teleportation of wave packets of light up to a bandwidth of 10 MHz while preserving strongly nonclassical superposition states.

In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.The team employed a mind-boggling set of quantum manipulation techniques to achieve this, including squeezing, photon subtraction, entanglement and homodyne detection.The results pave the way for high-speed, high-fidelity transmission of information, according to Elanor Huntington, a professor at the University of New South Wales in Australia who was part of the study.“If we can do this, we can do just about any form of communication needed for any quantum technology,” she said in a news release.

Instead of using ones and zeroes, quantum computers store data as qubits, which can represent one and zero simultaneously. This superposition enables the computers to solve multiple problems at once. The new, faster teleportation process means scientists can move blocks of this quantum information around within a computer or across a network, Huntington said.Optics researcher Philippe Grangier at the Institut d’Optique in Palaiseau, France, said it was a major breakthrough.

“It shows that the controlled manipulation of quantum objects has progressed steadily and achieved objectives that seemed impossible just a few years ago,” he wrote in an editorial that accompanies the study.
