Index of refraction of germanium

April 27, 2020
Author(s)
John H. Burnett, Eric C. Benck, Simon G. Kaplan, Erik Stover, Adam Phenis
Measurements of the index of refraction of a sample of high-quality, single-crystal germanium using the minimum deviation refractometry method are presented for temperatures near 22 degC and for wavelengths in the range 2 micron to 14 micron. The standard

On Wackers Essential Equation in the Extrapolation Measurement Technique

October 6, 2019
Author(s)
Alexey J. Yuffa
The generalized three-antenna method is a standard method for measuring on-axis gain and polarization of an antenna without a priori knowledge. The cornerstone of the method is the use of the extrapolation technique and the key relationship in the

Progress on Single Photon Detector Efficiency Calibrations at NIST

June 14, 2017
Author(s)
Thomas Gerrits, John H. Lehman, Alan Migdall, Sae Woo Nam, Igor Vayshenker, Chih-Ming Wang
We report on our progress towards implementing a measurement service aimed at the calibration of single-photon detectors. We present how our calibration is tied to the calibration of our transfer standard optical fiber power meters. We also developed and

Planning Buildings that will Last

February 19, 2017
Author(s)
G J. Frohnsdorff, H Davies
In designing a building that will perform reliably over a specified time, a designer needs a vast amount of information about the performance of the available materials and components (hereafter referred to, collectively, as maerials) in the likely service

Pairwise Alignment of Chromatograms using a Fisher-Rao Metric

September 2, 2014
Author(s)
William E. Wallace, Anuj Srivastava, Kelly H. Telu, Yamil Simon
A new approach to aligning chromatograms is introduced and applied to examples of metabolite identification by liquid chromatography mass spectrometry (LC MS). A square root representation of the chromatogram’s derivative coupled with a Fisher Rao

Quantum Algorithms for Fermionic Quantum Field Theories

April 28, 2014
Author(s)
Stephen P. Jordan, Keith S. Lee, John Preskill
Extending previous work on scalar field theories, we develop a quantum algorithm to compute relativistic scattering amplitudes in fermionic field theories, exemplified by the massive Gross-Neveu model. The algorithm introduces new techniques to meet the

Detection-Loophole-Free Test of Quantum Nonlocality, and Applications

September 26, 2013
Author(s)
B. G. Christensen, Kevin McCusker, Joseph Altepeter, Brice R. Calkins, Thomas Gerrits, Adriana Lita, Aaron J. Miller, Krister Shalm, Sae Woo Nam, P. G. Kwiat
We present a source of entangled photons that violates a Bell inequality free of the "fair-sampling" assumption, by over 50 standard deviations, and with enough "efficiency" overhead to eventually perform a fully loophole-free test of local realism. The

Experimental test of an event-based corpuscular model modification as an alternative to quantum mechanics

February 13, 2013
Author(s)
Giorgio Brida, Ivo P. Degiovanni, Marco Genovese, Alan L. Migdall, Fabrizio Piacentini, Sergey Polyakov, Paola Traina
We present the first experimental test that distinguishes between an event-based corpus- cular model of the interaction of photons with matter and quantum mechanics. The test looks at the interference that results as a single photon passes through a Mach
