Quantum Dense Coding with Atomic Qubits

January 1, 2004
Author(s)
T Schaetz, Murray D. Barrett, Dietrich G. Leibfried, J Chiaverini, Joseph W. Britton, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
We report the implementation of quantum dense coding on individual atomic qubits with the use of two trapped 9Be+ ions. The protocol is implemented with a complete Bell measurement that distinguishes the four operations used to encode two bits of classical

Recent Advances in Quantitative Synthetic-Polymer Mass Spectrometry at NIST

January 1, 2004
Author(s)
William E. Wallace, Charles M. Guttman
Commensurate with NIST s mission to advance the state of quantitative measurement science we have worked to develop a method to determine absolute molecular mass distribution of synthetic polymers by mass spectrometry. Work has centered on using matrix
