The theory and practice of quantum computing have both developed dramatically in recent years. At the top, advances in theory and algorithms have taught us much about the nature of computational complexity and broadened the range of potential uses of quantum computers. At the bottom, physicists are investigating a breathtaking array of potential qubit storage and quantum gate technologies.

The research group is committed to theoretical research in quantum optics and quantum information processing. The members are the research staff of the Department of Quantum Optics and Quantum Information within the ranks of the Institute of Solid State Physics and Optics of the Wigner Research Centre in Budapest.

We study fundamental aspects of quantum theory through the analysis of relevant information processing tasks and algorithms. We are interested in the formulation of physical principles in terms of information processing possibilities.
