One of the long-term mission-projects of the Research Center Jülich is to contribute significantly to the development of a quantum computer. To this end, the Center is pursuing a broad portfolio of diverse research activities ranging from theoretical quantum information, to the large-scale simulation of quantum systems, to quantum optics and material science, and to the development of dedicated cryoelectronics for qubit control. As a joint initiative between Research Center Jülich and the RWTH Aachen University, the JARA Institute for Quantum Information is part of this development, and it is greatly profiting from the close collaboration with the following institutions at Research Center Jülich.

Peter Grünberg Institute for Theoretical Nanoelectronics (PGI-2)

The institute is directed by Prof. David DiVincenzo and investigates the emergence of new phenomena in near atomic-scale structures and their possible applications for information processing. Principal investigators at PGI-2 with a strong interest in quantum information are Dr. Mohammad Ansari, Dr. Roman Riwar and Prof. Maarten Wegewijs.

Peter Grünberg Institute for Quantum Control (PGI-8)

This institute, funded in 2019 and directed by Tommaso Calarco, focuses on the development of optimal quantum control techniques for improving the fidelity of quantum computer devices, and of software tools for the automatic calibration of quantum hardware. Both efforts aim at enabling the exquisite level of control required for scalable quantum computing.

Peter Grünberg Institute for Semiconductor Nanoelectronics (PGI-9)

The institute, directed by Prof. Detlev Grützmacher, conducts several experimental activities that are relevant for quantum information, including the development of photonic interfaces (Prof. Beata Kardynal), the growth and development of advanced materials for spin qubits (Dr. Mihail Lepsa, Dr. Alexander Pawlis and Dr. Gregor Mussler), as well as fundamental research on hybrid superconductor/semiconductor-nanowire devices and topological insulators (Prof. Thomas Schäpers and Dr. Peter Schüffelgen).

Quantum Information Processing Group

Another major player in the field of quantum information at Research Center Jülich is the “Quantum Information Processing Group” led by Prof. Kristel Michielsen at the Jülich Supercomputing Center (JSC), which has first-class expertise in large scale simulations of single- and multi-qubits superconducting devices.

Central Institute for Engineering, Electronics and Analytics – Electronic Systems (ZEA-2)

The institute, directed by Prof. Stefan van Waasen, has a broad expertise in circuit engineering and in systems architecture. It is collaborating with the Quantum Technology Group for developing low-temperature electronics for qubit control and read out. Project leader is Dr. Carsten Degenhart.

Helmholtz Nano Facility (HNF)

This state-of-the-art 1100 m² clean room facility with advanced nanofabrication capabilities represents a major asset for the fabrication of advanced qubit devices.
