Supercomputing and Simulation Science

The Institute for Advanced Simulation unites Simulation Sciences and supercomputing under one roof. Thus, disciplinary, methodic and technological competences can be combined to manage the future challenges in the Simulation Sciences.

Supercomputer JUWELS


Jülich Supercomputing Centre operates computers of the highest performance class. The supercomputers JUWELS and JURECA are currently among the most powerful supercomputers in the world.

Der Dynamik lebender Materie auf der Spur

Life in Motion

Living matter is characterized by activity and energy consumption. What are the structures, dynamics, and collective behaviours, which develop under such non-equilibrium conditions? IAS-2 employs theoretical methods and numerical simulations to address such questions in systems from macromolecules to cells and tissues.


Quantum Information Processing

IAS-3 works at the fundamental level on the theory of quantum information processing, developing new concepts for qubits and multi-qubit modules. 

Protein folded

HPC-based multi-scale molecular simulations

IAS-5/INM-9 develops and applies HPC-based multi-scale molecular simulation tools, along with structural bioinformatics and data science approaches, to investigate molecular processes playing important roles for neuronal (dys-)function. This knowledge is then exploited for in silico ligand design.

Three bottleneck experiments with varying crowdsizes

Crowd and fire dynamics

The subinstitute’s main focus of research is on crowd and fire dynamics in the context of civil engineering and safety science.


Der D-Wave Quantenannealer an seinem neuen Standort im JUNIQ-Gebäude am Forschungszentrum Jülich

Europe’s First Quantum Computer with More Than 5,000 Qubits Launched at Jülich

A quantum annealer with more than 5,000 qubits has been put into operation at Forschungszentrum Jülich. The Jülich Supercomputing Centre (JSC) and D-Wave Systems, a leading provider of quantum computing systems, today launched the company’s first cloud-based quantum service outside North America. The new system is located at Jülich and will work closely with the supercomputers at JSC in future. The annealing quantum computer is part of the Jülich UNified Infrastructure for Quantum computing (JUNIQ), which was established in autumn 2019 to provide researchers in Germany and Europe with access to various quantum systems.

Optisches Schalten für die Informationsverarbeitung (künstlerische Darstellung)

Can Lasers Speed Up Computers?

Only a single laser pulse is theoretically needed to reverse the magnetisation of an elementary ferromagnet. This was demonstrated by junior researcher Hanan Hamamera during her doctoral thesis at Forschungszentrum Jülich and RWTH Aachen University. This "optical switching" is a promising way to store data ultra-fast by means of laser light. Until now, up to several hundred laser pulses have been routinely needed for such a single switching process.
