This paper provides a review of the most important and widely used Quantum Key Distribution systems and then describes our recently proposed scheme based on Subcarrier Multiplexing that opens the possibility of parallel Quantum Key Distribution. We report the first-ever ex perimental implementation of parallel quantum key distribution using this technique showing a maximum multiplexing gain.
