Ultimately cryptographers want some form of quantum repeater--in essence, an elementary form of quantum computer that would overcome distance limitations. A repeater would work through what Albert Einstein famously called "spukhafte Fernwirkungen," spooky action at a distance. . Anton Zeilinger and his colleagues at the Institute of Experimental Physics in Vienna, Austria, took an early step toward a repeater when they reported in the August 19, 2004, issue of Nature that their group had strung an optical-fiber cable in a sewer tunnel under the Danube River and stationed an "entangled" photon at each end. The measurement of the state of polarization in one photon (horizontal, vertical, and so on) establishes immediately an identical polarization that can be measured in the other.

Imagine, if you will, a means of delivering encryption keys that is so secure that it's impossible to break because doing so would violate the laws of physics. In other words, the delivery method is so secure, it's protected by the very fabric of the universe.. . .. Imagine, if you will, a means of delivering encryption keys that is so secure that it's impossible to break because doing so would violate the laws of physics. In other words, the delivery method is so secure, it's protected by the very fabric of the universe. If that doesn't get your attention, think about this: What Dr. Hughes is working with is a way to encode information on individual photons. He then sends these encoded photons to a receiver that can measure their characteristics and determine from those characteristics the data that the encoding represents. That's right: He's imprinting information on individual subatomic particles. The link for this article located at ZDNet is no longer available. .
