Joseph A. Hagmann, Xiqiao Wang, Pradeep N. Namboodiri, Richard M. Silver, Curt A. Richter
… (CMOS) devices that power existing computing technology, which continue to scale down in size as … in silicon is an exciting avenue towards the pursuit of quantum computing architectures due to long spin-coherence3 and …

Developing an Appropriate Heat Treatment Protocol for Additively Manufactured Alloy 718 for Oil and Gas Applications

March 23, 2023
Author(s)
Mark R. Stoudt, James Zuback, Carelyn E. Campbell, Maureen E. Williams, Kil-Won Moon, Carlos R. Beauchamp, Mark Yunovich
The combination of strength, corrosion resistance, and excellent weldability makes Alloy 718 an attractive alloy for additive manufacturing (AM) applications, but the AM build process generates considerable residual stresses, and large compositional and

Bipolar Waveform Synthesis with an Optically Driven Josephson Arbitrary Waveform Synthesizer

April 19, 2022
Author(s)
Justus Brevik, Dahyeon Lee, Anna Fox, Yiwei Peng, Akim Babenko, Joe Campbell, Paul Dresselhaus, Franklyn Quinlan, Samuel P. Benz
… a high-fidelity 1 kHz bipolar voltage waveform with a quantum-based amplitude that can be directly related to … current pulses have enabled the first demonstration of quantum-based bipolar waveform synthesis with an optical drive. We measured the quantum locking range with respect to several operating …

Web-enabled, Real-time, Quality Assurance for Machining Production Systems

April 19, 2012
Author(s)
John L. Michaloski
In order to maintain the close control of production quality, frequent measurement and process parameter adjustments are desirable. In the discrete parts industry, part inspection is intended to be a metric for the process quality but quality control is

Self-Bayesian Aberration Removal via Constraints for Ultracold Atom Microscopy

October 29, 2021
Author(s)
Ian Spielman, Emine Altuntas
… high numerical aperture (NA) optics, as is the case for quantum gas microscopy. These high NA objectives involve many … to loss and light scattering, making them unsuitable for quantum back-action limited "weak" measurements. We employ a … correction method for achieving optimal microscopy of quantum objects. This reconstruction relies on a high quality …

A Novel Peak Detection Algorithm for Use in the Study of Machining Chip Segmentation

November 7, 2007
Author(s)
Eric P. Whitenton, Robert W. Ivester, Jarred C. Heigel
The study of how metal deforms and flows as parts are machined yields important insights into the metal cutting process. Improvements in high-speed digital imaging and image processing software promise to improve our understanding of the tool-workpiece

Pauli blocking of atom-light scattering

November 18, 2021
Author(s)
Christian Sanner, Lindsay Sonderhouse, Ross Hutson, Lingfeng Yan, William Milner, Jun Ye
… Transition rates between coupled states in a quantum system depend on the density of available final … demonstration of suppressed light scattering in a quantum degenerate Fermi gas. We systematically measured the … factor on the temperature and Fermi energy of a strontium quantum gas and achieved suppression of scattering rates by …

Entity Authentication Using Public Key Cryptography

February 18, 1997
Author(s)
National Institute of Standards and Technology (NIST), James Foti
[Withdrawn October 19, 2015] This standard specifies two challenge-response protocols by which entities in a computer system may authenticate their identities to one another. These may be used during session initiation, and at any other time that entity
