Abstract
Systems and methods of authenticating and/or communicating key and/or data between communication parties using quantum channels are provided. In some embodiments, authentication may be provided during transmission (including at various stages), without transmission, before transmission, and/or without keys. Such systems and methods allow authentication to be performed on a bit-by-bit basis using the same quantum communication channel. Further, these systems and methods prevent an eavesdropper from gaining useful information, and/or allow man-in-the-middle attacks to be detected.
