Physicist Discovers How to Teleport Energy

First, they teleported photons, then atoms and ions. Now one physicist has worked out how to do it with energy, a technique that has profound implications for the future of physics.

Today, building on a number of papers published in the last year, Hotta outlines his idea and its implications. The process of teleportation involves making a measurement on each one an entangled pair of particles. He points out that the measurement on the first particle injects quantum energy into the system. He then shows that by carefully choosing the measurement to do on the second particle, it is possible to extract the original energy.

All this is possible because there are always quantum fluctuations in the energy of any particle. The teleportation process allows you to inject quantum energy at one point in the universe and then exploit quantum energy fluctuations to extract it from another point. Of course, the energy of the system as whole is unchanged.

He gives the example of a string of entangled ions oscillating back and forth in an electric field trap, a bit like Newton's balls. Measuring the state of the first ion injects energy into the system in the form of a phonon, a quantum of oscillation. Hotta says that performing the right kind of measurement on the last ion extracts this energy. Since this can be done at the speed of light (in principle), the phonon doesn't travel across the intermediate ions so there is no heating of these ions. The energy has been transmitted without traveling across the intervening space. That's teleportation.

There is a growing sense that the properties of the universe are best described not by the laws that govern matter but by the laws that govern information. This appears to be true for the quantum world, is certainly true for special relativity, and is currently being explored for general relativity. Having a way to handle energy on the same footing may help to draw these diverse strands together.

Interesting stuff. There's no telling where this kind of thinking might lead.

It is very interesting stuff. And apart from the black-and-white views of some physicists and science-commentators, the imagination that surrounds this sort of research is quite incredible. Can you imagine the multitude of applications such technology could take on. 

Harnessing this "power" may not necessarily occur in a commercial/true application sense in my lifetime, but it still gets the mind racing about how it could be used. 

Oh and check out some of the comments from the original article (http://www.technologyreview.com/blog/arxiv/24759/) - I did get a laugh!

I am NOT a God Particle - and did you know? The Large Hadron Collider is 'being sabotaged from the future'

In a bizarre sci-fi theory, Danish physicist Dr Holger Bech Nielsen and Dr Masao Ninomiya from Japan claim the LHC startup has been delayed due to nature trying to prevent it from finding the elusive Higgs boson, or "God particle".

Last year, Professor Brian Cox of Manchester University told the UK Telegraph that LHC scientists had received threatening emails and phone calls demanding that the experiment be halted.

But Prof Cox, ex-keyboardist for 1990's pop group D:REAM, dismissed the hysteria in rock-star style.

"Anyone who thinks the LHC will destroy the world is a tw--," he said.

The LHC is set to start up again next month.

 

Now was it the Mayan calendar that when converted ended in 2012? Of course we all should know that 2012 will see the end of our known world and time. And of course, this would be the ideal time for the LHC to be successful in its attempts to recreate the conditions that created the "God Particle".

Do I believe? Oh why the hell not. If nothing else, 'doomsdayers' and other such kooks get their moment so I figure, lets join in the fun!

Do I really think the LHC will cause a black hole and suck the living daylights (literally) from our dimension? Sure, why not, I am yet to hear why it wouldn't! Not really. Its just one sciencey-dude (oh I have a PHD and played keyboards in D:Ream! So you should believe me!) saying "no, nooo, nothing to worry about, don't be a twat about it..." (I am paraphrasing here!)...and other sciencey-dudes with equal qualification it seems warning of armageddon!

So do you believe? Bring it on CERN, get that big hadron wheel spinning, it can only be a better show than the Perth Wheel, the London Eye and all those other silly wheels that have popped up all over the place!

Its a sign you know?! It is, truly...now worship the wheel and hold on to your seats we're in for a bumpy ride!

p.s. I am NOT a God Particle...but secretly, I wish I was ;)
