The Next Generation of Current Measurement for Ionization Chambers

Ryan P. Fitzgerald, Denis E. Bergeron, Dean G. Jarrett, Neil M. Zimmerman, Carine Michotte, Hansjoerg Scherer, Stephen Giblin, Steven Judge
Re-entrant ionization chambers (ICs) are essential to radionuclide metrology and nuclear medicine for maintaining standards and measuring half-lives. Metrology

Broadband Optomechanical Sensing at the Thermodynamic Limit

Feng Zhou, Yiliang Bao, Ramgopal Madugani, David A. Long, Jason J. Gorman, Thomas W. LeBrun
Cavity optomechanics has enabled precision measurements with unprecedented levels of sensitivity, including the detection of attonewton forces, nanoparticles

Dielectric loss extraction for superconducting microwave resonators

Corey Rae H. McRae, Russell Lake, Junling Long, Mustafa Bal, Xian Wu, Battogtokh Jugdersuren, Thomas Metcalf, Xiao Liu, David P. Pappas
The investigation of two-level-state (TLS) loss in dielectric materials and interfaces remains at the forefront of materials research in superconducting quantum

Frequency-comb spectroscopy on pure quantum states of a single molecular ion

Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz, Yiheng Lin, Michael E. Harding, Philipp N. Plessow, Tara M. Fortier, Scott A. Diddams, Dietrich G. Leibfried, David R. Leibrandt
Spectroscopy is a powerful tool for studying molecular properties and is commonly performed on large thermal ensembles of molecules that are perturbed by

NIST Time and Frequency Bulletin

Kelsey A. Rodriguez
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST

Certified Quantum Measurement of Majorana Fermions

Emanuel H. Knill, Abu Ashik Md. Irfan, Karl H. Mayer, Gerardo Ortiz
We present a quantum self-testing protocol to certify measurements of fermion parity involving Majorana fermion modes. We show that observing a set of ideal

Targeted enrichment of 28Si thin films for quantum computing

Ke Tang, Hyun S. Kim, Aruna N. Ramanayaka, David S. Simons, Joshua M. Pomeroy
We report on the growth of isotopically enriched 28Si epitaxial films with precisely controlled enrichment levels, ranging from natural abundance ratio of 92.2%

Dynamic Heterogeneity and Collective Motion in Star Polymer Melts

Jack F. Douglas, Jinpeng Fan, Hamed Emamy, Francis W. Starr, Alexandros Chremos
While glass formation of linear chain polymers has been widely explored, comparatively little is known about glass formation in star polymer melts. We study the

Microwave-based arbitrary cphase gates for transmon qubits

George S. Barron, Fernando A. Calderon-Vargas, Junling Long, David P. Pappas, Sophia E. Economou
Superconducting transmon qubits are of great interest for quantum computing and quantum simulation. A key component of quantum chemistry simulation algorithms
