Device having a quantum interference between bit and qubit for eavesdropping detection and two-state quantum cryptography non-orthogonal

摘要

This is a method and apparatus for performing a secure quantum cryptography communication system using a two-state non-orthogonal. To encode the bit value of each qubit, the transmitting station to prepare the quantum system in the state of one of the orthogonal two states. Then, by measuring the interference between qubits and qubit reveals eavesdropping whether attempted. To assess the eavesdropping attacks made in the spacing of the quantum system, the state of the evidence used.
