Quantum Information Science & Technology Grand Challenge LDRD
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 form 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.
Seismic Event Detection
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.
