Abstract
A method and apparatus for reducing unauthorized access of an information stream. The information stream is received at a node along a path to a destination node. The information stream comprises information bits and quantum bits that are interspersed with each other. A portion of the quantum bits are examined at the node along the path. An occurrence of unauthorized access to the information stream is indicated when an original entangled state of the portion of the quantum bits is absent.
