David Kribs obtained his PhD in Pure Mathematics from the University of Waterloo. He was then awarded an NSERC postdoctoral fellowship and held visiting positions at the University of Iowa, Purdue University, Lancaster University and the Institute for Quantum Computing (IQC). In 2003 he took  a position in the Department of Mathematics & Statistics at the University of Guelph, where he is presently Professor and Chair. His current research interests are primarily in the mathematics of quantum information; with particular emphasis on quantum error correction, entanglement theory, quantum cryptography, and the connections between theoretical and experimental quantum information science. Outside of academics, he enjoys spending time with his family, reading, and playing sports, especially ice hockey.

PHY 373

Jan Kycia's research group, the Kycia Low Temperature Group, works on the experimental investigation of quantum mechanical properties of sub-micron and micron scaled superconducting devices. In particular superconducting single electron transistors (sSETs) and superconducting quantum interference devices (SQUIDs). They are focusing on gaining a better understanding of how dissipation and the environment affect the states of the devices. They also study the 1/f noise in Josephson junctions. This 1/f noise may be an intrinsic limitation to the coherence time of superconductor-based qubits.

Gerardo Ortiz is in the Physics Department at the University of Indiana in Bloomington and also an affiliate member with the Theoretical Division, Los Alamos National Laboratory.

The quest to explore the ultimate limits and principles of quantum physics is out there. Quantum technologies are no longer a theorist's dream. For example, commercial quantum cryptography devices have become available. Ortiz is interested in studying foundational, software, and hardware aspects of quantum computation and information. Because of the exciting recent development of new algorithms, such as Shor's factoring and Grover's quantum search, that solve difficult problems on a quantum computer using algorithms that would be impractical on a classical computer, it is easy to overlook the fact that Feynman's original proposal for quantum computers was for the purpose of solving quantum physics problems.

Simulation of physical phenomena using quantum devices is one of his areas of research. He is also concerned with topics of potential overlap between his two research disciplines, where feedback from one field may help to resolve significant problems in the other. After all, a quantum computer is a quantum many-body system. What are the concepts from quantum information that one can use to study or predict phenomena in condensed matter physics? Similarly, what concepts can be borrowed from condensed matter to quantify measures of information? These are fundamental open questions. Designing and building a quantum computer or a quantum simulator is a ultimate example of topics that meet the boundaries of both disciplines. Cold atom physics is another.
