quantum community

Abstract: In recent years, the notion of magic in quantum physics – originally confined to more esoteric quantum information processing subfields – has attracted the attention of the community of quantum many-body physics, quantum chaos and complexity, high-energy physics, AdS-CFT and the foundations of quantum mechanics. In this colloquium, we will give a survey of what quantum magic is, how it can be measured, and why we should care (and why and when we should not).

Speakers: Prof. Alioscia Hamma & Dr. Salvatore F.E. Oliviero

Fascinating phenomena can arise when ensembles of quantum particles interact in a correlated fashion. Emblematic instances are fractional quantum Hall states, which realize special types of quantum fluids with extraordinary properties, such as fractionalized charges and anyonic statistics. In this talk, we will first explore how state-of-the-art quantum simulation techniques are bringing these concepts into cold-atom experiments.

Speakers: Prof. Nathan Goldman & Ass. Prof. Julian Leonard

In the first qmeets talk, Professor Silke Weinfurtner and Dr. Patrik Svancara from the University of Nottingham will introduce quantum simulations of curved spacetimes around rotating compact objects like black holes. They’ll reveal how quantum tornadoes—giant vortices in superfluid helium—can help decode signals captured by gravitational wave detectors, bringing us closer to understanding the cosmos.
