61. Femtosecond frequency comb measurement of absolute frequencies and hyperfine coupling constants in cesium vapor
Topic: Physics
Published: 4/29/2010
Authors: Jason Stalnaker, Vela Mbele, Vladislav Gerginov, Tara Michele Fortier, Scott A Diddams, Leo Hollberg, C E Tanner
Abstract: We report measurements of absolute transition frequencies and hyperfine coupling constants for the 8S1/2 , 9S1/2 , 7D3/2 , and 7D5/2 states in 133 Cs vapor. The stepwise excitation through either the 6P1/2 or 6P3/2 intermediate state is perform ...

62. Femtosecond-Laser-Based Optical Clockwork with Instability < 6.3 {multiply} 10^u-16^ in 1 s
Topic: Physics
Published: 1/1/2002
Authors: Scott A Diddams, Leo W. Hollberg, L -S Ma, Lennart Robertsson

63. Femtotesla atomic magnetometry in a microfabricated vapor cell
Topic: Physics
Published: 12/20/2010
Authors: William C. Griffith, Svenja A Knappe, John E Kitching
Abstract: We describe an optically pumped ^u87^Rb magnetometer with 4.5 fT/Hz^u1/2^ sensitivity when operated in the spin-exchange relaxation free (SERF) regime. The magnetometer uses a microfabricated vapor cell, consisting of a cavity etched in a 1 mm thick ...

64. Formation and Control of Coulomb Crystals in Trapped Ion Plasmas
Topic: Physics
Published: 1/1/1998
Authors: X -P Huang, John J Bollinger, Wayne M Itano, Joseph N Tan, Branislav M. Jelenkovic, T B Mitchell, David J Wineland

65. Fourier, Gauss, Fraunhofer, Porod and the Shape from Moments Problem
Topic: Physics
Published: 1/17/2012
Author: Gregg M. Gallatin
Abstract: We show how the Fourier transform of a shape in any number of dimensions can be simplified using Gauss' law and evaluated explicitly for polygons in two dimensions, polyhedra three dimensions, etc. We also show how this combination of Fourier and Gau ...

66. Frequency Comparison of Two High-Accuracy Al+ Optical Clocks
Topic: Physics
Published: 2/17/2010
Authors: Chin W. Chou, David Hume, J.C. Koelemeij, David J Wineland, Till P Rosenband
Abstract: We have constructed an optical clock with a fractional frequency inaccuracy of 8.6e-18, based on quantum logic spectroscopy of an Al+ ion. A simultaneously trapped Mg+ ion serves to sympathetically laser-cool the Al+ ion and detect its quantum state. ...

67. Generation and characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP
Topic: Physics
Published: 11/15/2011
Authors: Thomas Gerrits, Martin J Stevens, Burm Baek, Brice R. Calkins, Adriana Eleni Lita, Scott C Glancy, Emanuel H Knill, Sae Woo Nam, Richard P Mirin, Robert Hadfield, Ryan Bennink, Warren Grice, Sander N. Dorenbos, Tony Zijlstra, Teun Klapwijk, Val Zwiller
Abstract: We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show a raw (corrected) Hong-Ou-Mandel interference with 86 % (90 %) visibility and a circular joint spectral probability distribution with ...

68. Generation of Ultrastable microwaves via optical frequency division
Topic: Physics
Published: 6/26/2011
Authors: Tara Michele Fortier, Matthew Steven Kirchner, Jennifer A. Taylor, James C Bergquist, Yanyi Jiang, Andrew D Ludlow, Christopher W Oates, Till P Rosenband, Scott A Diddams, Franklyn J Quinlan, Nathan D. Lemke
Abstract: A frequency-stabilized femtosecond laser optical frequency comb serves as a source of microwave signals having very low close-to-carrier phase noise. Comparison of two independent systems shows combined absolute phase noise of -100 dBc/Hz at an o ...

69. Generation of optical Schrödinger cat states by number-resolved squeezed photon subtraction
Topic: Physics
Published: 7/23/2010
Authors: Thomas Gerrits, Scott C Glancy, Tracy S. Clement, Brice R. Calkins, Adriana Eleni Lita, Aaron J. Miller, Alan L Migdall, Aaron J Miller, Sae Woo Nam, Richard P Mirin, Emanuel H Knill
Abstract: We have generated and measured an approximation of an optical Schrödinger cat state by photon subtraction from squeezed vacuum. Figure 1 shows the experimental scheme. Photons are probabilistically subtracted from squeezed vacuum and detected with a ...

70. Generation of optical coherent-state superpositions by number-resolved photon subtraction from the squeezed vacuum
Topic: Physics
Published: 9/9/2010
Authors: Thomas Gerrits, Scott C Glancy, Tracy S. Clement, Brice R. Calkins, Adriana Eleni Lita, Aaron Miller, Aaron J. Miller, Alan L Migdall, Sae Woo Nam, Richard P Mirin, Emanuel H Knill
Abstract: We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sen ...
