Partnering with Los Alamos National Laboratory, Sandia’s Ground-Based Nuclear Detonation Detection team has developed a 400-processor distributed computing system capable of processing more than 14 million seismic event signals. From this, researchers are able to realize a three-dimensional seismic-pressure-wave-velocity model of the entire Earth. Sandia can then deliver to its customers a capability to more accurately compute the locations of new seismic events, especially those that might be due to clandestine underground nuclear test detonations.

The Quantum Information Science & Technology Grand Challenge LDRD architecture team achieved its goals of designing an error-corrected “logical” qubit. This task used advanced mathematical and computing techniques to evaluate Si qubit systems from the atomic-scale modeling of the problems of quantum dots all the way to predictive simulations of error correction, which is considered one of the project’s most impressive technical achievements. Sandia’s published logical qubit design leveraged in-house expertise in optimization, scheduling, quantum information, and electronics. (1100, 1400, 1700, 8900, 9300) DS&A, IHNS, NW

The translation of domain names (e.g., www.sandia.gov) to Internet addresses using the Domain Name System (DNS) is fundamental to Internet usability. DNS security (DNSSEC) helps protect this essential service from compromise. However, DNSSEC is complex, and misconfiguration is prevalent, inhibiting DNS functionality. DNSViz is a web-based tool developed for DNSSEC visualization to aid administrators in understanding and troubleshooting DNSSEC deployments. It has been used by federal agencies complying with the US government’s DNSSEC mandate, as well as a broader DNS community. (8900) IES
