An Optical Clock Based on a Single Trapped Hg + Ion

January 1, 2001
Author(s)
Scott A. Diddams, T Udem, K R. Vogel, Christopher W. Oates, E A. Curtis, W D. Lee, Wayne M. Itano, Robert E. Drullinger, James C. Bergquist, Leo W. Hollberg
Microwave atomic clocks have been the de facto standards for precision time and frequency metrology over the past 50 years, finding widespread use in basic scientific studies, communications, and navigation. However, with its higher operating frequency, an

Decoherence-Free Quantum Memory Using Trapped Ions

January 1, 2001
Author(s)
D Kielpinski, V Meyer, M A. Rowe, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
We demonstrate a decoherence-free quantum memory of one qubit. By encoding the qubit into the decoherence-free subspace (DFS) of a pair of trapped 9Be+ ions, we protect the qubit from environment-induced dephasing that limits the storage time of a qubit

Experimental Violation of Bell's Inequalities with Efficient Detection

January 1, 2001
Author(s)
M A. Rowe, D Kielpinski, V Meyer, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
Local realism is the idea that objects have definite properties whether or not they are measured, and that measurements of these properties are not affected by events taking place sufficiently far away. Einstein, Podolsky and Rosen used these reasonable

Primary Atomic Frequency Standards at NIST

Donald Sullivan, James C. Bergquist, Robert E. Drullinger, Wayne M. Itano, Steven R. Jefferts, D W. Lee, D Meekhof, Thomas E. Parker, F L. Walls, David J. Wineland

Recent Results in Trapped-Ion Quantum Computing at NIST,

January 1, 2001
Author(s)
D Kielpinski, A Ben-kish, Joseph W. Britton, V Meyer, M A. Rowe, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
We review recent experiments on entanglement, Bell's inequality, and decoherence-free subspaces in a quantum register of trapped 9Be+ ions.

Decoherence of Quantum Superpositions Through Coupling to Engineering Reservoirs

January 1, 2000
Author(s)
C J. Myatt, B E. King, Q A. Turchette, C A. Sackett, D Kielpinski, Wayne M. Itano, W M. Monroe, David J. Wineland
The theory of quantum mechanics applies to closed systems. In such ideal situations, a single atom can, for example, exist simultaneously in a superposition of two different spatial locations. In contrast, real systems always interact with their
