Improved transfer of quantum information using a local memory
Vittorio Giovannetti, Daniel Burgarth
We demonstrate that the quantum communication between two parties can be significantly improved if the receiver is allowed to store the received signals in a quantum memory before…
From perfect to fractal transmission in spin chains
Gabriele De Chiara, Davide Rossini, Simone Montangero +1
Perfect state transfer is possible in modulated spin chains, imperfections however are likely to corrupt the state transfer. We study the robustness of this quantum communication p…
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…
Classical versus quantum errors in quantum computation of dynamical systems
Davide Rossini, Giuliano Benenti, Giulio Casati
We analyze the stability of a quantum algorithm simulating the quantum dynamics of a system with different regimes, ranging from global chaos to integrability. We compare, in these…
