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

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

EUV spectra from N-shell ions of Gd, Dy and W

Author(s)
Deirdre Kilbane, John D. Gillaspy, Yuri Ralchenko, Joseph Reader, G. O'Sullivan
Measurements of extreme ultraviolet radiation from gadolinium, dysprosium and tungsten ions with an open n=4 shell were performed at the National Institute of

A novel apparatus to measure reflected sunlight from the Moon

Author(s)
Claire E. Cramer, Gerald T. Fraser, Keith R. Lykke, John T. Woodward IV, Alan W. Smith
We describe a new apparatus for measuring the spectral irradiance of the Moon at visible wavelengths. Our effort builds upon the United States Geological Survey

High quantum-efficiency photon-number-resolving detector for photonic on-chip information processing

Author(s)
Brice R. Calkins, Paolo L. Mennea, Adriana E. Lita, Benjamin Metcalf, Steven Kolthammer, Antia A. Lamas-Linares, Justin Spring, Peter C. Humphreys, Richard P. Mirin, James Gates, Peter Smith, Ian Walmsley, Thomas Gerrits, Sae Woo Nam
The integrated optical circuit is a promising architecture for the realization of complex quantum optical states and information networks. One element that is

On integer solutions of x^4+y^4-2z^4-2w^4=0

Author(s)
Dustin Moody, Arman S. Zargar
In this article, we study the quartic Diophantine equation x^4+y^4-2z^4-2w^4=0. We find non-trivial integer solutions. Furthermore, we show that when a solution

Spectral response of an upconversion detector and spectrometer

Author(s)
Paulina S. Kuo, Oliver T. Slattery, Yong-Su Kim, Jason S. Pelc, M. M. Fejer, Xiao Tang
We theoretically and experimentally investigate the spectral response of an upconversion detector and discuss implications for its use as an infrared

Spiral Resonators for On-Chip Laser Frequency Stabilization

Author(s)
Scott A. Diddams, Hansuek Lee, Myoung-Gyun Suh, Tong Chen, Jiang Li, Kerry J. Vahala
Frequency references are indispensable to radio, microwave, and time keeping systems, with far reaching applications in navigation, communi- cation, remote

An atomic clock with 10-18 instability

Author(s)
Andrew D. Ludlow, Nathan M. Hinkley, Jeffrey A. Sherman, Nate B. Phillips, Marco Schioppo, Nathan D. Lemke, Kyle P. Beloy, M Pizzocaro, Christopher W. Oates
Atomic clocks have been transformational in science and technology, leading to innovations such as global positioning, advanced communications, and tests of

Feeling Small: Exploring the tactile perception limits

Author(s)
Lisa Skedung, Martin Arvidsson, Jun Y. Chung, Christopher Stafford, Birgitta Berglund, Mark W. Rutland
The human finger is exquisitely sensitive in distinguishing different materials, but the question remains as to what length scales are capable of being
