QuApps2021 — International Conference on Applications of Quantum Technologies
13 Sep 2021 - 15 Sep 2021 • Düsseldorf, Germany
Quantum technology will change the future! Right now is the time to set the course for quantum technologies and its applications, whereas certain attention focusses on room temperature technologies. QuApps 2021 prepares the definition of the quantum technology roadmap until 2030. QuApps 2021 will be a recurring event to present and discuss relevant applications material properties and process technologies for quantum applications – from the engineering and market point of view. Prominent keynote speakers will provide insights into potential markets and relevant technologies that will or already have reached market maturity. The range of topics extend from quantum applications in various markets such as quantum sensing, processing of quantum materials, metrology or communication to peripheral and enabling technologies. Partners from basic research come together with partners from industry to pave the way of quantum elements to our life, combining new quantum technologies with state of the art solutions in processing, assembly or control.

Autumn School on Correlated Electrons: Simulating Correlations with Computers
20 Sep 2021 - 24 Sep 2021 • Jülich, Germany
The combinatorial growth of the Hilbert space makes the many-electron problem a grand challenge. Progress relies on the development of non-perturbative methods, based on either wavefunctions or self energies. This made, in recent years, calculations for strongly-correlated materials a reality. These simulations draw their power from three sources: theoretical advances, algorithmic developments and the raw power of massively parallel supercomputers. Turning to quantum hardware could give quantum materials science the ultimate boost. Before quantum parallelism can be exploited, however, many questions, algorithmic and engineering, need to be addressed. The school will provide students with an overview of the state-of-the-art of many-body simulations and the promises of quantum computers. After introducing the basic modeling techniques and the concept of entanglement in correlated states, lectures will turn to methods that do not rely on wavefunctions, comparing density functional theory, the GW method and dynamical mean-field theory. Advanced lectures will broaden the discussion, addressing topics from the Luttinger-Ward functional to non-equilibrium Green functions. As a glimpse of future possibilities, the basics of quantum computing and its possible uses in materials simulations will be explained. The goal of the school is to introduce advanced graduate students and up to the full range of modern approaches for the realistic simulations of strongly correlated materials with computers.
