Physicists have “teleported” quantum information farther than ever in a new study reported Wednesday (Sept. 5).

This kind of teleportation isn’t quite what Scotty was “beaming up” on television’s Star Trek, but it does represent a kind of magic of its own. While Star Trek’s teleporters transport people from place to place instantaneously, quantum teleportation sends information.

A team of scientists from Austria, Canada and Germany have now beamed the quantum state of a particle of light from one island to another 89 miles (143 kilometers) away.

“One can actually transfer the quantum states of a particle — in our case a photon — from one location to another location without physically transferring this photon itself,” explained physicist Xiaosong Ma of the Institute for Quantum Optics and Quantum Information at the Austrian Academyof Sciences in Vienna.

To do this, the researchers started out with three particles: one particle to be teleported, and two “entangled” particles. Entanglement is one of the most bizarre implications of the theory of quantum mechanics, which governs the physics of tiny particles. When two particles are entangled, they become connected in such a way that, even if separated over vast distances, an action performed on one affects the other.

In the recent experiment, all three photons started out on the island of La Palma, one of the Canary Islands off the coast of Spain. One of the entangled photons was then sent through the air 89 miles to the Canary Island of Tenerife. Since the particles were entangled, when a measurement was made of the quantum states of the two particles on La Palma, it affected the particle on Tenerife, too, allowing the first particle to essentially be recreated in a new location without traversing the distance.

This achievement beat the previous quantum teleportation distance record of 60 miles (97 km), set by a Chinese research group just months ago. It represents a significant step toward establishing a “quantum internet” that could allow messages to be sent more securely, and calculations to be completed more quickly, scientists say.

“The quantum internet is predicted to be the next-generation information processing platform, promising secure communication and an exponential speed-up in distributed computation,” the researchers write in a paper detailing their experiment published online Wednesday in the journal Nature.

The next step will be to establish quantum teleportation between Earth and orbiting satellites.

“The future goal of our research work will be to do such experiments on the satellite level,” Ma told LiveScience. “This will enable intercontinental quantum information exchange.”

Ghost DNA

DNA Teleportation Nobel Prize winner Luc Montagnier describes a phenomenon in which DNA emits electromagnetic signals of its own construction, “ghost DNA” that can be mistaken by enzymes as the real deal and replicated in another place. Essentially, it’s DNA teleportation. Montagnier, et al.

A Nobel prize winning scientist who shared the 2008 prize for medicine for his role in establishing the link between HIV and AIDS has stirred up a good deal of both interest and skepticism with his latest experimental results, which more or less show that DNA can teleport itself to distant cells via electromagnetic signals. If his results prove correct, they would shake up the foundations upon which modern chemistry rests. But plenty of Montagnier’s peers are far from convinced.

The full details of Montagnier’s experiments are not yet known, as his paper has not yet been accepted for publication. But he and his research partners have made a summary of his findings available. Essentially, they took two test tubes – one containing a fragment of DNA about 100 bases long, another containing pure water – and isolated them in a chamber that muted the earth’s natural electromagnetic field to keep it from muddying the results. The test tubes were housed within a copper coil emanating a weak electromagnetic field.

Montagnier and his team say this suggests DNA emits its own electromagnetic signals that imprint the DNA’s structure on other molecules (like water). Ostensibly this means DNA can project itself from one cell to the next, where copies could be made – something like quantum teleportation of genetic material, a notion that is spooky on multiple levels.

Naturally, there is plenty of skepticism to go around regarding these findings, ranging from outright dismissal to measured doubt. Indeed, it’s a pretty radical notion: DNA replicating itself through “ghost imprints” rather than the usual cellular processes. More details will emerge when the paper is published in a peer-reviewed journal, as it is likely to be. The findings will then have to be repeated in multiple independent studies to be considered valid, something that will take some time. In the meantime, expect these findings to draw equal parts intrigue and skeptical scrutiny.
