Simulation on quantum authentication
- 30 Downloads
This paper divides into two main parts. The first one discusses authentication of quantum messages. The protocol proposed in  for one qubit message-length case is especially considered. The protocol uses a shared EPR pair as a secret key. In the second part, it is shown how such a protocol can be simulated using the Quantum-Octave package. Quantum-Octave is a set of functions for a Matlab-like numerical environment allowing calculations with general density matrices.
