Quantum Information - Theory

The theory group of the institute pursues a variety of topics in both practical and fundamental quantum information science. Solid state quantum information processing devices, either based on spins or superconductors, are a real possibility for the future.

Our theoretical work seeks to find improved ways for these qubits to function and to work together in a system. These goals motivate very fundamental studies in a diverse set of areas, including many-body physics, the theory of quantum error correction codes, the theory of quantum control, and quantum computational complexity. The following pages provide more information on the individual research topics.

Researchers in the theory group get to work on real-life problems in making quantum computers work, designing new algorithms for the simulations of many-body quantum systems, and working out the fundamental properties of quantum entanglement in a noisy world. They are involved in direct collaborations with researchers at the Jülich Research Center, with groups throughout Europe (e.g., at Paris, Delft, Gothenberg, Zürich), and with established (e.g., IBM) and start-up organizations elsewhere in the world.
