Bounds on Information Propagation in Disordered Quantum Spin Chains
How fast can information propagate through a locally interacting system? For classical systems an essentially universal answer to this question is that the velocity of information propagation is bounded (often only approximately) by an effective speed of light. It is a more subtle issue to formulate equivalent velocity bounds for quantum systems because they can encode quantum information in th...

متن کاملQuantum communication beyond the localization length in disordered spin chains.
We study the effects of localization on quantum state transfer in spin chains. We show how to use quantum error correction and multiple parallel spin chains to send a qubit with high fidelity over arbitrary distances, in particular, distances much greater than the localization length of the chain.
متن کاملAnomalous diffusion in disordered media and random quantum spin chains
Using exact expressions for the persistence probability and for the leading eigenvalue of the Fokker-Planck operator of a random walk in a random environment, we establish a fundamental relation between the statistical properties of anomalous diffusion and the critical and off-critical behavior of random quantum spin chains. Many exact results are obtained from this correspondence, including th...
