New Quantum way to send messages.

In what could eliminate the risk of sensitive information falling into the wrong hands, scientists have discovered a new way to send secure messages which can only be read by someone at an agreed location.

An international team has developed a new "quantum communication" process that delivers unprecedented security — in fact, it ensures that even if an encryption password falls into the wrong hands, a secure message can only be seen by a recipient at the right location.

Team leader Prof. Robert Malaney at the University of New South Wales said: "This takes communications security to a level that hasn't previously been available. With this process you can send data to a person at a particular location. "If they are not at that location the process would detect that and you can stop the communication.

This is a new application that you can deploy on current and emerging quantum networks. "It opens up a range of new information security applications for both fiber and wireless communication networks. There would be many industries and organizations, banks for example, that would be interested in delivering
information content in the sure knowledge a recipient is at an agreed upon location."
