MQV Colloquium: Martin Ringbauer

The MQV Colloquia feature interdisciplinary talks given by local as well as invited international experts. The colloquia, which are accessible to a worldwide audience via videoconference, cover all aspects of quantum technologies, with a focus on MQV research activities. The goal of the series is to establish and strengthen connections with quantum-technology experts worldwide and to provide a platform for education and scientific exchange for and with the local quantum ecosystem.

"Quantum Information Processing with Qudits"

Martin Ringbauer – Uni Innsbruck


Current quantum computers and simulators are almost exclusively built for binary information processing. Yet, the underlying quantum information carriers are almost always inherently multilevel systems. Similarly, many quantum simulation applications are naturally formulated in terms of high-dimensional Hilbert spaces. I will discuss the opportunities and challenges for universal quantum information processing with qudits in a trapped-ion system. I will then show how we can use these systems not only to natively simulate high-dimensional problems such as lattice gauge theories, but also to drastically improve the experimental overheads in the characterization of quantum states and the training of variational circuits.

Short bio

Martin Ringbauer received his PhD in experimental quantum optics from the University of Queensland, Australia in 2016. He then worked as a postdoctoral researcher in quantum photonics at Heriot-Watt University in Scotland. In 2018 he joined the University of Innsbruck, to work on quantum information processing with trapped ions. His research interests cover quantum computing and quantum simulation, with a particular focus on the development of new approaches based on high-dimensional trapped-ion qudits.  He has been awarded the ERC Starting Grant in 2022.
