German Researchers Take Next Step In Quantum Communications
2013-04-03 14:44:48

Brett Smith for redOrbit.com - Your Universe Online Quantum-based communications is still in its infancy, but the technology is widely expected to become used as the next generation of secure data transfer. According to a new report in Nature Photonics, a group of German physicists has announced the successful transmission of a quantum security key from an aircraft to a ground station via laser, overcoming one of the technology´s biggest hurdles: the ability to transmit and receive...

Photons Teleported 60 Miles By Chinese Researchers

A team of Chinese physicists have shattered the record for quantum teleportation, teleporting photons approximately six times further than the previous best, according to various news reports published Friday. A team of physicists hailing from the University of Science and Technology of China in Shanghai were able to teleport particles more than 97 kilometers, or over 60 miles, said Popular Science's Dan Nosowitz. That smashes the prior standard of more than 10 miles (16-plus...

Quantum Network Created Based On Interfaces Between Single Atoms And Photons

Brett Smith for Redorbit.com Quantum physicists have made a leap forward in subatomic particle communication by connecting two separate labs 21-meters apart using two atoms and a photon, according to a report published in the April 12 issue of Nature. A group from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany said they have demonstrated the ability to construct a basic two-node network that could be expanded because of its high efficiency and fidelity....

Discovery moves quantum networks closer to reality Researchers at the University of Calgary, in Canada, collaborating with the University of Paderborn, in Germany, are working on a way to make quantum networks a reality and have published their findings in the journal Nature. A similar finding by a group at the University of Geneva, in Switzerland is reported in the same issue. "We have demonstrated, for the first time, that a crystal can store information encoded into entangled quantum...

GENEVA, Switzerland, October 9 /PRNewswire/ -- The SwissQuantum testbed network was set up in Geneva by the University Of Geneva, the University of Applied Sciences of Western Switzerland and the company id Quantique in order to demonstrate long-term operation of quantum cryptography technology in a meshed network setting. Contrary to quantum networks previously deployed, it is used to carry real traffic and is independently tested. Quantum Cryptography is a technology that allows...

European scientists say they have built the world's largest quantum key distribution network to transmit secure quantum encrypted information. Officials said 41 research and industrial organizations constructed the eight-node, mesh network consisting of an average 12-mile to 19-mile link, with the longest link being 51 miles. The scientists said their achievement is a huge step toward practical implementation of secure quantum-encrypted communication networks. The Institute of Physics in...

Researchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.With an average link length of 20 to 30 kilometres, and the longest link being 83 kilometres, the researchers from organisations such as the AIT Austrian Institute of Technology (formerly Austrian Research Centers), id Quantique,...
