Beating the channel capacity limit for linear photonic superdense coding
channel capacity limit linear photonic superdense coding
2010/10/21
Dense coding is arguably the protocol that launched the field of quantum communication [1]. Today,however, more than a decade after its initial experimental realization [2], the channel capacity remai...
The generation of Entangled Qudits and their Application in Probabilistic Superdense Coding
generation of Entangled Qudits Application Probabilistic Superdense Coding
2013/7/3
A scheme of the generation of entangled qutrits is presented, and then is generalized to entangled ququads and entangled qudits. With the entangled qutrits, an experimental scheme of probability super...
