This might seem like an interdisciplinary non-sequitur, 
but I draw your attention to this sentence in the final 
paragraph:

"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."

Implications for the future of geographical thought.....?


Physicist Discovers How to Teleport Energy

http://www.technologyreview.com/blog/arxiv/24759/

Wednesday, February 03, 2010

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.

In 1993, Charlie Bennett at IBM's Watson Research Center 
in New York State and a few pals showed how to transmit 
quantum information from one point in space to another 
without traversing the intervening space.

The technique relies on the strange quantum phenomenon 
called entanglement, in which two particles share the same 
existence. This deep connection means that a measurement 
on one particle immediately influences the other, even 
though they are light-years apart. Bennett and company 
worked out how to exploit this to send information. (The 
influence between the particles may be immediate, but the 
process does not violate relativity because some 
informatiom has to be sent classically at the speed of 
light.) They called the technique teleportation.

That's not really an overstatement of its potential. Since 
quantum particles are indistinguishable but for the 
information they carry, there is no need to transmit them 
themselves. A much simpler idea is to send the information 
they contain instead and ensure that there is a ready 
supply of particles at the other end to take on their 
identity. Since then, physicists have used these ideas to 
actually teleport photons, atoms, and ions. And it's not 
too hard to imagine that molecules and perhaps even 
viruses could be teleported in the not-too-distant future.

But Masahiro Hotta at Tohoku University in Japan has come 
up with a much more exotic idea. Why not use the same 
quantum principles to teleport energy?

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.

Just how we might exploit the ability to teleport energy 
isn't clear yet. Post your suggestions in the comments 
section if you have any.

But the really exciting stuff is the implications this has 
for the foundations of physics. Hotta says that his 
approach gives physicists a way of exploring the 
relationship between quantum information and quantum 
energy for the first time.

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.
