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.

Oxytocin and Autism: Study on A Receptor Variant Provides New Insights into the Cellular Origin of the Disorder

Oxytocin is known as the "love hormone". It strengthens social bonding and promotes trust and empathy. Researchers from Regensburg and Jülich have now demonstrated, how genetic variations of the receptor affect the hormone signaling inside brain cells. Their findings provide a better understanding why nasal sprays with oxytocin are not always helpful to treat autistic patients and they point to alternative strategies that could lead to new therapies in the long term.

3D-PLI

Science: How Brain Research Makes New Demands on Supercomputing

In the latest issue of Science, Katrin Amunts and Thomas Lippert explain how advances in neuroscience demand high-performance computing technology and will ultimately need exascale computing power. The construction of a supercomputer capable of 10 to the power of 18 computing operations per second has been considered the next big step in supercomputing for many years.

Superrechner JUWELS

Measuring the AI Performance of Europe's Fastest Supercomputer

Researchers at Forschungszentrum Jülich and the Karlsruhe Institute of Technology (KIT) wanted to know how Europe's fastest supercomputer performs when it comes to training neural networks. – and have subjected it to a new performance test for artificial intelligence, or AI for short. The enormous computing power is required, among other things, for the development of language models and weather forecasts with AI. The results were presented at the world's largest supercomputing conference, SC21.

CroMa

Large-Scale Experiment with 1,500 Volunteers Commences

Jülich, 8 October 2021 – A total of some 1,500 volunteers are expected to participate in a large-scale scientific experiment that started on Friday, 8 October in the Mitsubishi Electric HALLE in Düsseldorf. Over the four days of the experiment, the volunteers will walk around the venue on a number of different routes in order to recreate conditions on crowded and overcrowded railway platforms. They will be guided by researchers from Forschungszentrum Jülich, the University of Wuppertal, and Ruhr University Bochum as part of the CroMa project, which is funded by the Federal Ministry of Education and Research (BMBF) within its research programme for civil security. The results of the experiment will help to improve the safety and performance of railway stations when faced with high passenger numbers.

Skyrmion Research: Braids of Nanovortices Discovered

A team of scientists from Germany, Sweden and China has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions could provide a possible basis for innovative concepts in information processing that offer better performance and lower energy consumption.

Neural Networks: Chaos Pays Off

Creative geniuses have known it all along: Chaos improves your intellectual capacity. At least, it may be useful when it comes to networked neurons, as a scientific paper of Forschungszentrum Jülich has now shown. The newly discovered mechanism could also help speed up artificial neural networks used in artificial intelligence and machine learning applications.

AI against Climate Change: Environment Minister Svenja Schulze Visits Forschungszentrum Jülich

Federal environment minister Svenja Schulze paid a visit to Forschungszentrum Jülich on 28 June 2021 as part of her summer tour. Information about energy-efficient supercomputing and the use of artificial intelligence (AI) to benefit climate and environmental protection were the focal point of the visit. Jülich researchers want to apply AI methods to identify any risks associated with climate change at an early stage.

JURECA-DC

Supercomputer for Large Data Volumes

Forschungszentrum Jülich upgraded the modular supercomputer JURECA which is now capable of 23.5 quadrillion computations per second (petaflops). One particular focus of the new system is on processing gigantic volumes of data. This was achieved by installing the module JURECA-DC – “DC” stands for “data-centric” – delivered by the French vendor Atos and operated by the cluster software of the German company ParTec.

How Quantum Systems Keep a Memory of Their Environment

Many quantum devices – electrical, optical or otherwise – respond in a delayed manner to a control pulse. The systems still show traces of past behaviour. Researchers at RWTH Aachen University and Forschungszentrum Jülich have now shown how this "memory" can be modelled more easily. The results are relevant, among other things, for applications in quantum technology, the development of which is still a challenge due to difficulties in modelling.
