MQV-Kolloquien sind interdisziplinäre Vorträge, die sowohl von lokalen als auch von eingeladenen internationalen Experten gehalten werden. Die Kolloquien, die per Videokonferenz für ein weltweites Publikum zugänglich sind, decken alle Facetten der Quantentechnologien ab, wobei der Schwerpunkt auf den Forschungsaktivitäten des MQV liegt. Ziel der Reihe ist es, Verbindungen zu Experten:innen auf dem Gebiet der Quantentechnologie weltweit herzustellen und zu stärken und eine Plattform für Bildung und wissenschaftlichen Austausch in und mit dem lokalen Quanten-Ökosystem zu bieten.
"Realization and Characterization of Topological States on Quantum Processors"
Frank Pollmann – TUM
Abstract
The interplay of quantum fluctuations and interactions can yield novel quantum phases of matter with fascinating properties. Understanding the physics of such systems is a very challenging problem as it requires to solve quantum many body problems—which are generically exponentially hard to solve on classical computers. In this context, universal quantum computers are potentially an ideal setting for simulating the emergent quantum many-body physics. In this talk, I will discuss two different classes of quantum phases: First, we consider symmetry protected topological (SPT) phases and show that a topological phase transitions can be simulated using shallow circuits. We then utilize quantum convolutional neural networks (QCNNs) as classifiers and introduce an efficient framework to train them. Second, we focus on the realization of topological ordered phases and simulate the braiding of anyons. We then investigate phase transitions between different symmetry enriched topological (SET) phases.
