21. Preserving quantum coherence using optimized open-loop control techniques
Topic: Quantum Physics
Published: 5/16/2010
Authors: Michael J. Biercuk, Hermann Uys, Aaron Vandevender, Nobuyasu Shiga, Wayne M. Itano, John J Bollinger
Abstract: We describe experimental and theoretical studies of open-loop quantum control techniques known as dynamical decoupling (DD) for the suppression of decoherence-induced errors in quantum systems. Our experiments on trapped atomic ion qubits demonstra ...

22. Propagation of Vortex Electron Wave Functions in a Magnetic Field
Topic: Quantum Physics
Published: 7/5/2012
Authors: Gregg M. Gallatin, Ben McMorran
Abstract: The physics of coherent beams of photons carrying axial orbital angular momentum (OAM) is well understood and such beams, sometimes known as vortex beams, have found applications in optics and microscopy. Recently electron beams carrying very large ...

23. Quantum radiometry
Topic: Quantum Physics
Published: 5/2/2009
Authors: Sergey V Polyakov, Alan L Migdall
Abstract: We review radiometric techniques that take advantage of photon counting and stem from the quantum laws of nature. We present a brief history of metrological experiments and review the current state of experimental quantum radiometry.

24. Synthetic Magnetic Fields for Ultracold Neutral Atoms
Topic: Quantum Physics
Published: 12/3/2009
Authors: Yu-Ju Lin, Robert L. Compton, Karina K. Jimenez Garcia, James V Porto, Ian B Spielman
Abstract: Neutral atomic Bose condensates and degenerate Fermi gases have realized important many-body phenomena in their most simple and essential forms, without many of the complexities usually associated with material systems. A rich source of physics in el ...

25. Tests of a Two-Photon Technique for Measuring Polarization Mode Dispersion With Subfemtosecond Precision
Topic: Quantum Physics
Published: 1/1/1999
Authors: Eric Dauler, Gregg Jaeger, A Muller, Alan L Migdall
Abstract: An investigation is made of a recently introduced quantum interferometric method capable of measuring polarization mode dispersion (PMD) on sub-femtosecond scales, without the usual interferometric stability problems associated with such small ...

26. The statistical strength of experiments to reject local realism with photon pairs and inefficient detectors
Topic: Quantum Physics
Published: 3/18/2010
Authors: Yanbao Zhang, Emanuel H Knill, Scott C Glancy
Abstract: Because of the fundamental importance of Bell's theorem, a loophole-free demonstration of a violation of local realism is highly desirable. Here, we study violations of local realism involving photon pairs. We quantify the experimental evidence again ...
