The world's first quantum network, integrated with the Internet, is now operating in the Boston area. Its developers hope that the messages it sends will be secure from hackers and eavesdroppers for as long as imagination now extends.

    Talked about for decades, a quantum code key system joined to the Internet has now been demonstrated. It sends encoding and decoding keys as light pulses between Harvard and Boston universities and BBN Technologies, a hi-tech company in Cambridge, Mass. The network started operating in June.

    "Our team has been able to develop a laboratory curiosity into a working system that is being tested and refined for use in sending secure messages," says Harvard project scientist John Myers.
