Two non-orthogonal states quantum cryptography method and apparatus with inter-and inter-qubit interference for eavesdropper detection










Image Number 8 for United States Patent #7929690.

An apparatus and method for implementing a secure quantum cryptography system using two non-orthogonal states. For each qubit, the to emitter station prepares a quantum system in one of two non-orthogonal quantum states in the time-basis to code bit values. Intra- and inter-qubit interference is then used to reveal eavesdropping attempts. Witness states are used to help reveal attacks performed across the quantum system separation.
