Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers at the Niels Bohr Institute succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation. The experiments are conducted in the laboratories of the research group in the basement under the Niels Bohr Institute. There are two glass containers, each containing a cloud of billions of caesium gas atoms. The two glass containers are not connected to each other, but information is teleported from the one glass cloud to the other by means of laser light. The light is sent into the fi rst glass container and then that strange quantum phenomenon takes place, the light and gas become entangled. The fact that they are entangled means that they have established a quantum link – they are synchronised. Both glass containers are enclosed in a chamber with a magnetic fi eld and when the laser light (with a specifi c wavelength) hits the gas atoms, the outermost electrons in the atoms react –like magnetic needles – by pointing in the same direction. The direction can be up or down, and it is this direction that makes up quantum information, in the same way that regular computer information is made up of the numbers 0 and 1. The gas now emits photons (light particles) containing quantum information. The light is sent on to the other gas container and the quantum information is now read from the light and registered by a detector. The signal from the detector is sent back to the fi rst container and the direction of the atoms’ electrons are adjusted in relation to the signal. This completes the teleportation from the second to the fi rst container.
