High-fidelity laser-free universal control of trapped ion qubits

September 8, 2021
Raghavendra Srinivas, Emanuel Knill, Robert Sutherland, Alexander T. Kwiatkowski, Hannah M. Knaack, Scott Glancy, David J. Wineland, Shaun C. Burd, Dietrich Leibfried, Andrew C. Wilson, David T. Allcock, Daniel Slichter
Universal control of multiple qubits—the ability to entangle qubits and to perform arbitrary individual qubit operations—is a fundamental resource for quantum computing, simulation and networking. Qubits realized in trapped atomic ions have shown the

Certification of Standard Reference Materials(R) 2969 and 2970: Vitamin D Metabolites in Frozen Human Serum (Total 25-Hydroxyvitamin D Low Level) and (25-Hydroxyvitamin D2 High Level)

September 2, 2021
Grace Hahm, Michael Nelson, Johanna Camara, Blaza Toman
Standard Reference Materials (SRMs) 2969 and 2970 are intended for 1) use in validating methods for determining concentrations of 25-hydroxyvitamin D2 (25(OH)D2) and 25-hydroxyvitamin D3 (25(OH)D3) in human serum and plasma and 2) value assigning in house

Single-Zone Simulations Using FaTIMA for Reducing Aerosol Exposure in Educational Spaces

September 2, 2021
Lisa Ng, Dustin Poppendieck, Brian Polidoro, William Stuart Dols, Steven Emmerich, Andrew K. Persily
On March 11, 2020, the World Health Organization declared the novel coronavirus (COVID-19) outbreak a global pandemic. Following this announcement, school closures around the United States began, and starting in June 2020, many schools decided to reopen

Nanopore sensing: a physical-chemical approach

September 1, 2021
Joseph W. Robertson, Madhav Ghimire, Joseph Reiner
Protein nanopores have emerged as an important class of sensor, for the understanding of biophysical processes, such as molecular transport across membranes, and detection and characterization of biopolymers. We trace the development of these sensors from
