Australian scientists may have worked out the mystery of teleportation

ANU delves into teleportation technology
Secret in entanglement of beams of light
More: Technology news and reviews
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.

How many times does this story have to be announced....

I think it is about quantum teleportation, yet again. For example;

23 January 2009 ; "Scientists achieve first successful teleportation between two atoms a meter apart."
http://www.andhranews.net/Technology...irst-85762.asp

or 12th October 2007 ; "Beam me up: Just how close are we to teleportation?" (CNN) at http://edition.cnn.com/2007/TECH/sci...teleportation/

or 16th June 2004 ; "Teleportation breakthrough made" (BBC)
http://news.bbc.co.uk/2/hi/science/nature/3811785.stm

or 17 June 2002 ; "Australian teleport breakthrough" (BBC)
http://news.bbc.co.uk/2/hi/science/nature/2049048.stm

or 17 June 2002 "Scientists Report 'Teleported' Data"
http://www.timeenoughforlove.org/sav...portedData.htm

or 03 April 1993 "Is this teleportation as we know it?" (New Scientist)
http://www.newscientist.com/article/...-know-it-.html

Sure they might of done something different, but for the media it is just run-of-the-mill storylines! Suppose, old news is good news. At least it is recyclable....

I'm very sorry to have wasted your time by posting this. I didn't notice that it had been discussed on this forum prior, so I thought that some good folk might be interested. Again - my sincerest apologies. I'll Google everything I come across from now on and make reference after reference to it just in case, and be sure to include the obviously required bibliography.

I think your taking what I've said the wrong way. I never thought that it was discussed on the forum (I didn't actually look). I was just referring to the number of times this 'teleportation' has been reported in the media before - several times in fact by the same investigators.

No need for apologies - and really your posting the recent item just brings us all up to date! Ta!

As for wasting my time? No way José, very interesting subject in theory or practice, (We should also probably talk about force shields and phasers, which are even more interesting and just as improbable on the macro-scales. )

Do recommend you read some of Lawrence Krauss's works - like "The Physics of Star Trek" (1996). If I can recall it would take a temperature 1000 billion degrees, the energy of 100-megaton nuclear bomb and to transport a human being. This doesn't take the means of disassembling, sending a energy stream and reassemble that person. If you could put them into the transporter buffer, it would require a series of 100 Gb hard-drive 1,000 light years high, storing 10^28 kB or 10000000000000000000000000000 kB!!

Transferring, at say, 1.0 Gb per second it would take to load, then upload, 200 times the total age of the Universe!
Transporters... good idea... technologically near impossible!

No. I'm not really cranky at all!!

Really just the same old people doing the transporter experimentation have made similar 'announcements' before! Media just grabbing the headline to 'catch our eye' !

Funding for experimentation probably needs a boost!

Really. Couldn't be happier today. The Sun actually shone for a while!

Wow, Teleportaion huh....

Thanks for posting the story.
I was intrigued by this advancement in Technology.
Working with Electronics as I do ( in machine control ) I enjoyed it.

Thx.

Just gotta watch them Flies in the same cubicle as us when we teleport....

Professor. Lawrence Krauss is a noted physics popularist - making science fun. His two main "Star Trek" books are great, debunking what is mostly improbable to what is possible physics-wise. Good fun way to learn to think about physics!

Wikipedia gives a good summary too.... http://en.wikipedia.org/wiki/Lawrence_M._Krauss

[Glenhuon (Bill)]

It's fun to speculate though. How many advances in science would we have without imagination.
Anyway no danger of me getting into one of them things, I'll catch the next shuttle thank you

More mundane application of this could be in the realms of data communications (as hinted at in the article). Being able to stuff more bits through the fibre optics or getting around the tyrany of distance for long-haul, international comms. Would be agreat for medical imaging that deals with transmitting extremely large data between sites.

[avandonk]

Quantum entanglement cannot be used to transmit data or anything else faster than the speed of light. Sure the two 'particles' are linked for all time and space but if you interfere with one, you 'set' the other before it can be 'read' so no data is effectively transmitted.

I prefer to think of quantum entanglement as a means for everything in the Universe to be inextricably linked in some way we do not understand as at one time and place everything was in the putative singularity that gave rise to the big bang.

Yes, after I posted that I thought about the constant of speed of light in a vacuum, doh The bits can't get from a<>b any quicker...
