Theoretical Nanoelectronics

The quantum mechanical nature of matter is the basis of all functioning of electronic devices. We use techniques from many-body physics, from quantum statistical physics, and from the mathematics of topology, to analyze the properties of electrons in a wide range of present-day exploratory devices. Our work can enable the development of new qubits, and new approaches to building a quantum computer.

New method prevents quantum computers crash

Quantum information is fragile, which is why quantum computers must also be able to correct errors. But what if whole qubits are lost? Researchers at Forschungszentrum Jülich and RWTH Aachen University, in collaboration with Universities of Innsbruck and Bologna, are presenting a method in the journal Nature that allows quantum computers to keep going even if they lose some qubits along the way.


Tag des PGI 2020 - “Opportunities Through Change” and the annual Institute Assembly

Following on from last year’s very successful first “PGI-Tag”, this year’s Assembly will again be accompanied by entertaining and informative events. Due to the pandemic, this event mainly has to take place virtually. We are organising an online event from the Auditorium of the Central Library, which will enable everyone to participate and hopefully once more bring together the many different areas of the institute. 



Electronic Properties of Nanostructured Materials

Atomic order-disorder transitions or phase transitions like freezing-melting are among the most dramatic effects occurring in condensed matter.


Quantum Information Processing

We work at the fundamental level on the theory of quantum information processing, developing new concepts for qubits and multi-qubit modules.  We work closely with the experimental scientists in PGI-11.
