711. Timing in Telecommunications Networks
Topic: Physics
Published: 7/20/2011
Author: Judah Levine
Abstract: I describe the statistical considerations used to design systems whose clocks are compared using dial-up telephone lines or the Internet to exchange timing informaiton. The comparison is usually used to synchronize the time of a client system to the ...

712. Toward Spin Squeezing with Trapped Ions
Topic: Physics
Published: 9/23/2010
Authors: John J Bollinger, Hermann Uys, Michael Biercuk, Joseph Wright Britton
Abstract: Building robust instruments capable of making interferometric measurements with precision beyond the standard quantum limit remains an important goal in many metrology laboratories. We describe here the basic concepts underlying spin squeezing experi ...

713. Toward scalable ion traps for quantum information processing
Topic: Physics
Published: 3/16/2010
Authors: Jason Amini, Hermann Uys, Janus H. Wesenberg, Signe Seidelin, Joseph Wright Britton, John J Bollinger, Dietrich G Leibfried, Christian Ospelkaus, Aaron Vandevender, David J Wineland
Abstract: The basic components for a quantum information processor using trapped ions have been demonstrated in a number of experiments. To perform complex algorithms that are not tractable with classical computers, these components need to be integrated and s ...

714. Towards Quantum Degeneracy of Bosonic and Fermionic Potassium Atoms
Topic: Physics
Published: 11/1/1999
Authors: F S Cataliotti, Eric A Cornell, C Fort, M Inguscio, M Prevedelli, G M Tino
Abstract: These notes are devoted to a discussion of the results we obtained during the last two years in experiments of confinement and cooling of bosonic and fermionic potassium atoms towards quantum degeneracy. Further details on these experiments can be f ...

715. Towards a compact cold atom frequency standard based on coherent populatoin trapping
Topic: Physics
Published: 6/2/2010
Authors: Francois-Xavier R. Esnault, Elizabeth A Donley, John E Kitching
Abstract: We describe in this paper the main features of a cold atom CPT based frequency standard. We explain our particular CPT configuration and our experimental setup. as well as present simulations of the expected performance (stability and major systemati ...

716. Towards an all-digital time scale
Topic: Physics
Published: 7/31/2011
Authors: Stefania Romisch, Steven R Jefferts, Thomas Edward Parker
Abstract: The implementation of an all-digital time scale is under way at NIST, using a novel 8-channel, all-digital phase measurement system based on subsampling techniques. The phase measurement system is used to compare output signals from several commercia ...

717. Transatlantic 2.5 MChip/s Two-Way Satellite Time and Frequency Transfer with Surface Acoustic Wave Filters
Topic: Physics
Published: 7/31/2011
Authors: Victor Shufang Zhang, Thomas Edward Parker, Joseph Achkar, Daniele Rovera
Abstract: From August 2010 to April 2011, NIST and OP conducted an experiment of using surface acoustic wave (SAW) filters in transatlantic two-way satellite time and frequency transfer (TWSTFT) with 2.5 MChip/s pseudo-random noise (PRN) codes. The SAW filter ...

720. Trapped Ions and Laser Cooling IV
Topic: Physics
Published: 1/19/1996
Authors: James C Bergquist, John J Bollinger, Wayne M Itano, C R Monroe, David J Wineland
