Anderson If light is the standard messenger in communications technology, the messenger just got a bigger saddlebag. A recent discovery by five physicists from Scotland has opened the door to packing more information into a beam of light. The new discovery promises faster ways to send and receive quantum information, although right now, only through empty space. Nevertheless, it could lead to faster and better quantum cryptography and communications, with many more applications if it can be adapted for fiber optics. Photons -- those indivisible particles of light that carry every telephone and Internet communication for at least part of the journey -- have long been subject to clever tricks that enable them to carry as much information as possible....
