Tech-buffs, investors, IT industrialists, and boffins alike eagerly await the day when the science of quantum computing yields practical technology. Physicists of the Max Planck Institute of Quantum Optics (MPQ), recently published research that, they believe, has brought that pivotal day closer.
For many years, physicists have sought to create an information network far superior to today's by exploiting quantum phenomena. The team of German researchers have constructed the first vital component of such a network: a link between two atomic nodes over which information can be received, sent, and stored using a single photon. Successful exchanges of information recently took place in Garching, Germany, between two MPQ labs connected by a 60-meter fiber-optic cable. Though only a prototype, this rudimentary network could be scaled up to more complex and distanced quantum networks. The team reports their research in Nature.
