Entanglement-enhanced information transmission over a quantum channel with correlated noise

220 citations recorded by the source corpus.
We show that entanglement is a useful resource to enhance the mutual information of the depolarizing channel when the noise on consecutive uses of the channel has some partial correlations. We obtain a threshold in the degree of memory above which a higher amount of classical information is transmitted with entangled signals.

- Quantum channels with memory (2005, methodology): “Apparently, the first model of a quantum channel with memory was introduced by Macchiavello et al. in 2001: they gave an example of a qubit channel with Markovian correlated noise [10, 11] in which entangled input states may increase the transmission rate for classical information.”
