Quantum information processing with trapped ions



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 quantum information processing. However the techniques used have application in other areas of physics providing improvement in quantum limited measurement and fundamental tests of quantum mechanical principles, for example.
