A group of Danish research scientists headed by Professor Eugene Polzik at the Niels Bohr Institute (NBI), University of Copenhagen, have taken an important step forward in quantum teleportation between light and matter. The objective of the research is to develop a communication network based on quantum teleportation of information. The breakthrough was published in the 5 October issue of Nature.

Professor Eugen Polzik explains: "Teleportation is one of the most important building blocks in the quantum communication network of the future, and it will revolutionise communication with computers. The information is not coded and processed in the current 0 and 1 bits, but in quantum conditions which can exist in superposition conditions 0, 1, 2 etc. at the same time. It means that there can be a lot more information than with ordinary bits. Another important property is that the information coded in quantum superpositions in principle is completely secure."

The experiment conducted at NBI is the first example of quantum teleportation where light is used to transport the information, and where an atomic object, containing thousands of billions of atoms, is used to store this information. The news was reported by Comon.
