High-dimensional quantum key distribution with photonic orbital angular momentum


Conference Paper

© 2014 Optical Society of America. We experimentally demonstrate a quantum cryptography system based on photonic orbital angular momentum. The system achieves a channel capacity of 2.1 bits per sifted photon through the use of a 7-dimensional alphabet for encoding information.
