Machine learning solves complex quantum problems
Due to a new method, artificial neural networks, as used in machine learning, will be able to be trained quicker so as to be able to solve complex problems in quantum mechanics. For example, previously unexplained properties of a special state of matter, the quantum spin liquid, can be calculated, something that has not been possible with any previous method to date. This has been made possible by a new optimisation method developed by the Institute of Physics.
Honorary doctorate for Prof. Dieter Vollhardt
Prof. Dieter Vollhardt was awarded an honorary doctorate by the University of Warsaw last week in recognition of his scientific achievements and longstanding collaboration with theoretical physicists at the University of Warsaw.
Leading quantum mechanical research
The Centre for Electronic Correlations and Magnetism (EKM) was established in the early 1990s. Since then, it has become a top research institute in the field of quantum mechanics. The meeting of the scientific advisory board of the EKM in Augsburg, composed of leading experts in the field, confirms this.
Feenberg Medal für Augsburger Physiker
Dem theoretischen Physiker Dieter Vollhardt wurde in den USA die "2022 Feenberg Memorial Medal" verliehen. Vollhardt, ehemaliger Inhaber des Lehrstuhls für Theoretische Physik III/Elektronische Korrelationen und Magnetismus am Institut für Physik der Universität Augsburg, erhielt die hohe Auszeichnung zusammen mit Antoine Georges (Frankreich) und Gabriel Kotliar (USA).
Fundamentale Frage der Quantenphysik
Ein internationales Team von Physikern unter Beteiligung der Universität hat erstmals eine wichtige theoretische Vorhersage der Quantenphysik bestätigt. Die Berechnungen dazu sind so komplex, dass sie bislang selbst Supercomputer überforderten. Den Forschern gelang es jedoch, sie mit Methoden aus dem Bereich der künstlichen Intelligenz deutlich zu vereinfachen.
Paper: Reinforcement Learning for Digital Quantum Simulation
Digital quantum simulation on quantum computers provides the potential to simulate the unitary evolution of any many-body Hamiltonian with bounded spectrum by discretizing the time evolution operator through a sequence of elementary quantum gates. A fundamental challenge in this context originates from experimental imperfections, which critically limits the number of attainable gates...
