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…

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,…
