Scientists May Have Worked Out Teleportation

[Truthed]

AUSTRALIAN scientists have developed a new method for transmitting data with light that may lead to super-fast quantum computers and teleportation technology.

The research team from the Australian National University developed a new approach to generating quantum entanglement in beams of light using only two parts.

Quantum entanglement is a process in which two objects are linked together in such a way that any changes to the properties of one can be measured from the other regardless of the distance between them.

This process of linking particles has existed for a few years but team leader Dr Jiri Janousek says this new method allows it to be achieved in a much simpler way.

"Usually, when you want to generate entanglement you need a lot of sources of light and a lot of receivers but we found a way to use only one source and one receiver to generate and measure entanglement," Dr Janousek said.

Dr Janousek and his team's new method involves entangling two specially modified beams of light so that changes to the amplitude or phase of one beam can be measured with the other.

By only using two parts, Dr Janousek says, it allows the technology to be more easily scaled up opening a number of potential uses in technologies ranging from computing, communications and even teleportation.

"This finding is one more piece in the puzzle towards the future realisation of quantum computers, which would be many times faster and more powerful than existing computers," he said.

"For teleportation you again need a source of entangled beams, so in effect it could be used for teleportation as well."

But, Dr Janousek, says it will be a while before this technology works its way into any consumer devices.

"We always talk about 50 years as where we could get real machines that could use the technologies which we have developed so far.

"When you think about the example of a quantum computer you have a lot of pieces to research first, then you have to put it together. So we have made one of these pieces that is only a tiny bit of the whole idea," he said.

I wonder if they realize that Star Trek writers created teleportation because the shuttle craft model was not completed and the effects were too expensive for most of the shows. The teleporter was a last minute device created to get the crew to a planet, as the shuttle was going to be used instead.

Still, they may use the new information for faster than light communications, something that was also used in Star Trek.

this will work unless a fly gets in the chamber with you,then your dna will mix with its,and we all know the outcome on this.

These scientists made a beam of light disappear in one place and reappear in another a short distance away.

The achievement confirms that in theory teleportation is possible, at least for subatomic particles. Whether it can be done for larger systems such as atoms, remains as science fiction.

heres the formula for teleportation

I have written in depth here before regarding Quantum Computing and quantum mechanics (The Feynman Processor: Quantum Entanglement and the Computing Revolution) and included formulae (not block diagrams with it).....

In 1993 an international group of six scientists, including IBM Fellow Charles H. Bennett, confirmed the intuitions of the majority of science fiction writers by showing that perfect teleportation is indeed possible in principle, but only if the original is destroyed. In subsequent years, other scientists have demonstrated teleportation experimentally in a variety of systems, including single photons, coherent light fields, nuclear spins, and trapped ions. Teleportation promises to be quite useful as an information processing primitive, facilitating long range quantum communication (perhaps unltimately leading to a "quantum internet"), and making it much easier to build a working quantum computer. But science fiction fans will be disappointed to learn that no one expects to be able to teleport people or other macroscopic objects in the foreseeable future, for a variety of engineering reasons, even though it would not violate any fundamental law to do so.
