Experimental Realization of Neutron Helical Waves

May 11, 2022
Author(s)
Michael G. Huber, Charles W. Clark, Dmitry Pushin, Connor Kapahi, Lisa DeBeer-Schmitt, David Cory, Huseyin Ekinci, Melissa Henderson, Dusan Sarenac
Methods of preparation and analysis of structured waves of light, electrons, and atoms have been advancing rapidly. Despite the proven power of neutrons for material characterization and studies of fundamental physics, neutron science has not been able to

Measurements of Absolute, SI-traceable Lunar Irradiance with the Airborne LUnar Spectral Irradiance (air-LUSI) Instrument

May 5, 2022
Author(s)
John T. Woodward IV, Kevin Turpie, Thomas Stone, S. Andrew Gadsden, Andrew Newton, Stephen Maxwell, Steven Grantham, Thomas Larason, Steven W. Brown
The Airborne LUnar Spectral Irradiance (Air-LUSI) instrument is designed to make low uncertainty, hyperspectral measurements of the lunar spectral irradiance from an ER-2 aircraft from altitudes above 95 % to 99 % of the atmosphere. Measurements cover the

Critically Evaluated Spectral Data for Singly Ionized Carbon (C II)

May 4, 2022
Author(s)
Alexander Kramida, K. Haris
All available experimental data on the spectrum of singly ionized carbon have been critically analyzed. Measurement uncertainties of all published studies have been re-assessed. The scope of observational data includes laboratory emission spectra of arcs

Entanglement Thresholds of Doubly Parametric Quantum Transducers

April 29, 2022
Author(s)
Curtis Rau, Akira Kyle, Alexander T. Kwiatkowski, Ezad Shojaee, John Teufel, Konrad Lehnert, Tasshi Dennis
Doubly parametric quantum transducers, such as electro-optomechanical devices, show promise for providing the critical link between quantum information encoded in highly disparate frequencies such as in the optical and microwave domains. This technology

Quantum phase modulation with acoustic cavities and quantum dots

April 29, 2022
Author(s)
Poolad Imany, Zixuan Wang, Ryan DeCrescent, Robert Boutelle, Corey McDonald, Travis Autry, Samuel Berweger, Pavel Kabos, Sae Woo Nam, Richard Mirin, Kevin L. Silverman
Fast, efficient, and low-power modulation of light at microwave frequencies is crucial for chip-scale classical and quantum processing as well as for long-range networks of superconducting quantum processors. A successful approach to bridge the gap between
