An atomic boson sampler

May 8, 2024
Author(s)
Aaron Young, Shawn Geller, William Eckner, Nathan Schine, Scott Glancy, Emanuel Knill, Adam Kaufman

Robustness of the projected squeezed state protocol

May 8, 2024
Author(s)
Byron Alexander, John J. Bollinger, Mark Tame
Projected squeezed (PS) states are multipartite entangled states generated by unitary spin squeezing, followed by a quantum measurement and post-selection. They lead to an appreciable decrease in the state preparation time of the maximally entangled N

Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

May 8, 2024
Author(s)
Noah Schlossberger, Nik Prajapati, Samuel Berweger, Andrew Rotunno, Aly Artusio-Glimpse, Abrar Sheikh, Eric Norrgard, Christopher L. Holloway, Stephen Eckel
Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields

Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields

Single-electron states of phosphorus-atom arrays in silicon

May 8, 2024
Author(s)
Maicol Ochoa, Keyi Liu, Michal Zielinski, Garnett W. Bryant
We characterize the single-electron energies and the wavefunction structure of arrays with two, three, and four phosphorus atoms in silicon by implementing atomistic tight-binding calculations and analyzing wavefunction overlaps to identify the single

Usability for Poll Workers: A Voting System Usability Test Protocol

May 8, 2024
Author(s)
Dana Chisnell, Sharon J. Laskowski, Karen Bachmann, Svetlana Z. Lowry
In this paper, we discuss our efforts to develop a repeatable test protocol for assessing usability for poll workers – temporary election officials who ensure secure and private voting in voting places. The research described in this paper is part of a

Access Control on NoSQL Databases

May 7, 2024
Author(s)
Vincent C. Hu
NoSQL database systems and data stores often outperform traditional RDBMS in various aspects, such as data analysis efficiency, system performance, ease of deployment, flexibility/scalability of data management, and users' availability. However, with an

Cross-Sectional Melt Pool Geometry of Laser Scanned Tracks and Pads on Nickel Alloy 718 for the 2022 Additive Manufacturing Benchmark Challenges

May 7, 2024
Author(s)
Jordan Weaver, David Deisenroth, Sergey Mekhontsev, Brandon Lane, Lyle E. Levine, Ho Yeung
AM Bench is a NIST-led organization that provides a continuing series of additive manufacturing (AM) benchmark measurements, challenge problems, and conferences with the primary goal of enabling modelers to test their simulations against rigorous, highly

Hyperspectral dark-field microscopy of human breast lumpectomy samples for tumor margin detection in breast-conserving surgery

May 7, 2024
Author(s)
Jeeseong Hwang, Philip Cheney, Stephen Kanick, Hanh Le, David McClatchy, Helen Zhang, John Lu, Tae Joon Cho, Kimberly Briggman, David W. Allen, Wendy A. Wells, Brian Pogue
Hyperspectral dark-field microscopy (HSDFM) and data cube analysis algorithms demonstrate successful classification of various tissue types, including the detection of carcinoma regions in human post-lumpectomy breast tissues excised during breast

Williams
Reproducibility and validation are major hurdles for scientific development across many fields. Materials science in particular encompasses a variety of experimental and theoretical approaches that require careful benchmarking. Leaderboard efforts have

Laser tracker and terrestrial laser scanner range error evaluation by stitching

May 7, 2024
Author(s)
Balasubramanian Muralikrishnan, Braden Czapla, Vincent Lee, Craig Shakarji, Daniel S. Sawyer, Saure Matthias
Laser trackers (LTs) are dimensional measurement instruments commonly employed in the manufacture and assembly of large structures. Terrestrial laser scanners (TLSs) are a related class of dimensional measurement instruments more commonly employed in

Recovery pathway assessment of recycled HDPE for circular economy: Shorter-life vs longer-life products

May 7, 2024
Author(s)
Buddhika Hapuwatte, Ashley Hartwell, Matthew Triebe, Abheek Chatterjee, Nehika Mathur, Daniel Figola, Katherine Morris
High Density Polyethylene (HDPE) is a highly recyclable thermoplastic comprising 17% of all plastic produced. Yet, demand for recycled HDPE (r-HDPE) has outrun availability, partly due to manufacturers' interest in meeting sustainability goals and recycled
