Scientists Teleport Light and Matter

Scientists at the Niels Bohr Institute in Denmark have made a breakthrough in teleportation by successfully transmitting both light and matter over short distances in a split second.

Led by Professor Eugene Polzik of Copenhagen University, the experiment improves upon previous attempts at teleportation that could transmit either light or matter, but not both. Polzik and his team were also able to transmit their matter over half a meter, much longer than the previous record.

Teleportation between two single atoms had been done two years ago by two teams, but this was done at a distance of a fraction of a millimeter, said Polzik. Our method allows teleportation to be taken over longer distances because it involves light as the carrier of entanglement.

Polzik’s method is also capable of transmitting much more information than was previously possible. While previous methods could transmit a single atom across a short distance, Polzik’s experiment involved teleportation of a bundle comprised of billions of atoms.

And while we won’t be teleporting Klingons to and ‘fro any time soon, the advances in teleportation can be put to use in quantum computers. Quantum computers function by transmitting information while in its energy state, specifically manipulating the energy, motion and magnetic field of atoms. Such methods would be much faster and more efficient than standard computers, which use slower electrical signals.

It is really about teleporting information from one site to another site. Quantum information is different from classical information in the sense that it cannot be measured, Polzik said. It has much higher information capacity and it cannot be eavesdropped on. The transmission of quantum information can be made unconditionally secure.
