44th IFF Spring School

Quantum Information Processing

25 February - 08 March 2013 Jülich, Germany


The IFF Spring School & Quantum Information in Jülich

The IFF Spring Schools were first brought into being in 1970 by the "Jülich Institute of Solid State Research" (IFF). Since then, the schools have made it possible for students and young scientists to gain a two-week insight into a current topic related to condensed matter physics. In 2011, IFF was dissolved as part of a restructuring process within Forschungszentrum Jülich, and new institutes, namely the "Peter Grünberg Insitute" (PGI), the "Jülich Centre for Neutron Science" (JCNS) and the "Institute of Complex Systems" (ICS) were established. Together with the "Institute for Advanced Simulation" (IAS), they will continue to coordinate the IFF Spring Schools. The 44th Spring School 2013 will be organized by PGI-2: Theoretical Nanoelectronics.

Under the umbrella of the Juelich-Aachen Research Alliance (JARA), extensive activity is underway at the forefront of quantum information science at Juelich. The Institute for Quantum Information (IQI), in close cooperation with the PGI Institute for Theoretical Nanoelectronics, focuses on the many and growing connections between quantum information and condensed matter physics. Experimental groups work on the realization of quantum bits in single-spin quantum dots in semiconducting systems (both gallium-arsenide and silicon-germanium based). In cooperation with other experimental groups, emphasis is placed on the design and realization of functioning quantum-computing modules using current developments in circuit quantum-electrodynamics and superconducting qubits.

Concepts are also being developed for the next steps in the use of nanowire devices to realize arrays of Majorana qubits, within the context of a larger theoretical effort to define the possibilities and constraints involved in using Fermionic particles for quantum information processing. In simulation sciences, the group has led the way in developing new, entanglement-motivated representations of quantum states for the efficient simulation of properties in 2D spin systems.
