Realization of Quantum Error Correction

December 1, 2004
Author(s)
J. Chiaverini, D. Leibfried, T Schaetz, M D. Barrett, R. B. Blakestad, J. Britton, W M. Itano, J. D. Jost, Emanuel Knill, C. Langer, R Ozeri, David J. Wineland
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

Quantum information processing with trapped ions

July 25, 2004
Author(s)
Murray D. Barrett, Tobias Schaetz, J Chiaverini, Dietrich Leibfried, Joseph W. Britton, Wayne M. Itano, John D. Jost, Emanuel Knill, C. Langer, R Ozeri, David J. Wineland
We report experiments on the creation and manipulation ofmulti-particle entangled states of trapped atomic ions. The experiments reported here, quantum dense coding and quantum teleportation, constitute a significant step toward performing large-scale
