摘要
An apparatus and method for implementing a secure quantum cryptography system using two non-orthogonal states. For each qubit, the 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.
