Memory effects in quantum information transmission across a Hamiltonian dephasing channel
A. D'Arrigo, G. Benenti, G. Falci
We study a dephasing channel with memory, modelled by a multimode environment of oscillators. Focusing on the case of two channel uses, we show that memory effects can enhance the…

Bound entanglement in the XY model
D. Patané, R. Fazio, L. Amico
We study the multi-spin entanglement for the 1D anisotropic XY model concentrating on the simplest case of three-spin entanglement. As compared to the pairwise entanglement, three-…

Quantum Capacity of a dephasing channel with memory
Antonio D'Arrigo, Giuliano Benenti, Giuseppe Falci
We show that the amount of coherent quantum information that can be reliably transmitted down a dephasing channel with memory is maximized by separable input states. In particular,…
