A review on super dense coding over covariant noisy channels
arXiv:1305.7490 · doi:10.2478/qmetro-2013-0004
Abstract
We study the performance of the super dense coding protocol in the presence of quantum channels with covariant noise. We first consider the bipartite case and review in a unified way the case of general Pauli channels. We discuss both the cases of unitary and non-unitary encoding. We also study the multipartite scenario and investigate the case of many senders and one receiver.
