Local controllability of quantum networks

Burgarth, Daniel; Bose, Sougato; Bruder, Christoph; Giovannetti, Vittorio (2009)

We give a sufficient criterion that guarantees that a many-body quantum system can be controlled by properly manipulating the (local) Hamiltonian of one of its subsystems. The method can be applied to a wide range of ...
Memory Effects in spin-chain channels for information transmission

Bayat, Abolfazl; Burgarth, Daniel; Mancini, Stefano; Bose, Sougato (2008)

We investigate the multiple use of a ferromagnetic spin chain for quantum and classical communications without resetting. We find that the memory of the state transmitted during the first use makes the spin chain a ...
