| Abstract
|
:
|
One of the major scientific thrusts in recent years has been to try to harness quantum phenomena to increase dramatically the performance of a wide variety of classical information processing devices. In particular, it is generally accepted that quantum computers and communication systems promise to revolutionize our information infrastructure
