Light wave teleported without data loss

Light wave teleported without data loss

Until now, any attempt to teleport a light wave containing information resulted in a loss of integrity.

A Tokyo-based research team has succeeded in teleporting a beam of light without losing any data for the first time.

The machine that achieved the feat, known as the teleporter, provided the breakthrough in quantum communications with the first-ever transfer, or teleportation, of a particularly complex set of quantum information with no loss of integrity.

Similar devices have been able to transfer data over considerable distances, many kilometres in some cases, but have always suffered from data loss.

Professor Elanor Huntington, from the Australian Defence Force Academy (ADFA), claims that by transferring the information from one point to another, the breakthrough opens the door to high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via quantum communications networks.

According to the University of New South Wales, Huntington claims that 'one of the limitations of high-speed quantum communication at present is that some detail is lost during the teleportation process.' She describes it as 'the Star Trek equivalent of beaming the crew down to a planet and having their organs disappear or materialise in the wrong place. We’re talking about information but the principle is the same – it allows us to guarantee the integrity of transmission.

'Just about any quantum technology relies on quantum teleportation. The value of this discovery is that it allows us, for the first time, to quickly and reliably move quantum information around. This information can be carried by light, and it’s a powerful way to represent and process information. Previous attempts to transmit were either very slow or the information might be changed. This process means we will be able to move blocks of quantum information around within a computer or across a network, just as we do now with existing computer technologies.'

Do you think quantum computers will be with us in the next decade, or will the 'classical' computer continue to evolve to meet our needs? Let us know your thoughts in the forums.

One step closer till we can go to the toilet and it be instantly teleported to the waste facility!

Start with Stephen Hawking's A Briefer History of Time (the new one). Best guide to the world of general relativity and quantum mechanics there is. Engaging, witty, and not dry at all. :)

No. You really don't. Anything in depth enough to be useful also contains maths complex enough to hurt. Take my word for this.

I'm not after anything useful, just general interest.

Try something by Michio Kaku, he explains complex physics without going into too much maths

You're right. It shows where these people's heads are. Infantile, moronic, anal-retentive bedwetters, everyone. It's no wonder the sun set on the former British Empire.

Or even better; rebuild the world so that one area is converted into a closed complex of toilets where you can rent a toilet for life and telport to it when in need of relief.

This way you have loads of space at home plus you can get rid of the stench and no need to spend money buying toilet air freshners.

Sometimes I'm so full of great ideas. I'll patent it and setup my own quantum toilet enterprise

So, how long until this technology is used for streaming porn?

I think the guys at Bit Tech are now shaking their heads in dispear and wonder where it all went wrong. I guess they're thinking why bother at all with smart, interesting articles since all we (read I) think about are toilets

Yep, I'll second that. Sort of. I read the first one, (A Brief History of Time) which was mind-expandingly brilliant. If I remember rightly, the entire book contains only one single equation: E=mc2 (squared) - so it's not at all going to bombard with you with over-reaching maths and complexity.

Hawking has that wonderful ability of someone who truly understands his subject, whereby he can take the most esoteric, abstract and complex idea and then break it down and explain it in a way that makes it seem utterly simple. An absolute must read for anyone even vaguely interested in physics.

You must be reaaaallly optimistic, i give it about 3 days -.-, people are way too focused on porn to let something like mass pornographic vids and photos take longer than 3 days to integrate it into the new system.

Imagine being able to produce energy and then transport it hundred and thousands of miles away in seconds Mind boggling

Try Brian Greene's The Elegant Universe - http://www.amazon.co.uk/s/?ie=UTF8&keywords=an+elegant+universe&tag=googhydr-21&index=aps&hvadid=6533938985&ref=pd_sl_9lv39gw02b_e

Explains string theory from the basics in analogies that I could pick up easily. Brilliant read.

I guess Onlive gameservice would need this one.
