<http://i.bnet.com/blogs/blue_vortex_blur.jpg>A physicist has demonstrated
that teleportation of energy is possible, a discovery that has profound
implications for the study of physics.
*Masahiro Hotta* at Tohoku University <http://www.tohoku.ac.jp/english/>in
Japan showed that <http://arxiv.org/abs/1002.0200> teleportation of energy
is possible by using the quantum principles to transport information.
Relying on the quantum phenomenon called
“entanglement<http://en.wikipedia.org/wiki/Quantum_entanglement>”
— in which two particles share the same existence, meaning that a
measurement on one particle immediately influences the other despite being
light-years apart — Hotta’s idea involves making a measurement on each one
an entangled pair of particles.
<http://i.bnet.com/blogs/masahiro_hotta_tohoku_university_energy_teleportation.jpg>According
to Hotta, the measurement on the first particle injects quantum energy into
the system. By carefully choosing the measurement to do on the second
particle, it is possible to extract the original energy, Hotta says.
This is possible because there are always quantum fluctuations in the energy
of any particle. Teleportation allows you to inject quantum energy at one
point in the universe and then exploit quantum energy fluctuations to
extract it from another point, leaving the energy of the system as whole
unchanged.
Here’s *Technology Review* breaking the science
down<http://www.technologyreview.com/blog/arxiv/24759/>
:
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.
IBM’s Charlie Bennett first showed the world information teleportation in
1993 at the Watson Research Center in New York. Since quantum particles are
indistinguishable except for the information they carry, there is no need to
transmit them themselves — and since Bennett’s discovery, physicists have
been able to teleport photons, atoms, and ions.
The next step: the teleportation of molecules or viruses.
Hotta says the concept allows physicists for the first time to explore the
relationship between quantum information and quantum energy.

Is the universe governed by the laws of matter or information? After all
this, I’m not so sure.
