One-dimensional quantum cellular automata over finite, unbounded configurations
Pablo Arrighi, Vincent Nesme, Reinhard Werner
One-dimensional quantum cellular automata (QCA) consist in a line of identical, finite dimensional quantum systems. These evolve in discrete time steps according to a local, shift-…
Complementarity of Private and Correctable Subsystems in Quantum Cryptography and Error Correction
Dennis Kretschmann, David W. Kribs, Robert W. Spekkens
We make an explicit connection between fundamental notions in quantum cryptography and quantum error correction. Error-correcting subsystems (and subspaces) for quantum channels ar…
A Continuity Theorem for Stinespring's Dilation
Dennis Kretschmann, Dirk Schlingemann, Reinhard F. Werner
We show a continuity theorem for Stinespring's dilation: two completely positive maps between arbitrary C*-algebras are close in cb-norm iff we can find corresponding dilations tha…
Dynamical magnetic susceptibility in the lamellar cobaltate superconductor Na_xCoO_2H_2O
M. M. Korshunov, I. Eremin
We systematically analyze the influence of the superconducting gap symmetry and the electronic structure on the dynamical spin susceptibility in superconducting Na_xCoO_2H…
Satellite Observations of Separator Line Geometry of Three-Dimensional Magnetic Reconnection
C. J. Xiao, X. G. Wang, Z. Y. Pu +14
Detection of a separator line that connects magnetic nulls and the determination of the dynamics and plasma environment of such a structure can improve our understanding of the thr…
Calorimetric Evidence for a Fulde-Ferrell-Larkin-Ovchinnikov Superconducting State in the Layered Organic Superconductor κ_2_2$
R. Lortz, Y. Wang, A. Demuer +5
The specific heat of the layered organic superconductor -% (BEDT-TTF)Cu(NCS), where BEDT-TTF is bisethylenedithio-% tetrathiafulvalene, has been studied in magnetic fiel…
