Associate Professor Andreas Klappenecker was recently awarded a National Science Foundation Division of Computer and Communication Foundations (NSF CCF) grant for his continued research in improving the reliability of quantum computing.

His grant, “Fault-Tolerance with Subsytem Codes,” will be funded through 2013.

Quantum computing is a new paradigm in computing where information is stored in quantum mechanical systems. Quantum computing offers more efficient ways to solve certain computational tasks by taking advantage of quantum mechanical principles, such as entanglement and superposition, in its computational operations. Successful quantum information processing requires mechanisms that make the basic operations reliable.

“One problem that decreases the reliability of quantum mechanical systems is decoherence. The quantum systems carrying the information are surrounded by and interact with other quantum systems in an fashion that cannot be controlled. These interactions can derail the computation, unless we take proper countermeasures,” Klappenecker said.

“What we are looking to do is encode the quantum information redundantly. This project will extend the theory of subsystem codes, a class of quantum error-correcting codes that have rich structure and the potential to realize fault-tolerant operations more efficiently.”

Andreas Klappenecker is associate professor in the Department of Computer Science and Engineering at Texas A&M. He received his Ph.D. in Computer Science from the University of Karlsruhe in Germany in 1998. He joined Texas A&M University in 1999 as a visiting assistant professor of mathematics, and worked shortly as a research associate at the University of Karlsruhe before accepting his current position.

His research interests include the design and analysis of algorithms, quantum algorithms and quantum error-correcting codes. His research is supported by grants from the National Science Foundation.
