    "abstract": "We study the capacity of d-dimensional quantum channels with memory modeled\nby correlated noise. We show that, in agreement with previous results on Pauli\nqubit channels, there are situations where maximally entangled input states\nachieve higher values of mutual information than product states. Moreover, a\nstrong dependence of this effect on the nature of the noise correlations as\nwell as on the parity of the space dimension is found. We conjecture that when\nentanglement gives an advantage in terms of mutual information, maximally\nentangled states saturate the channel capacity.",
