Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…

Entangled states maximize the two qubit channel capacity for some Pauli channels with memory
C. Macchiavello, G. M. Palma, S. Virmani
We prove that a general upper bound on the maximal mutual information of quantum channels is saturated in the case of Pauli channels with an arbitrary degree of memory. For a subse…
