Quantum Simulating Lattice Gauge Theories – High-Energy Physics at Ultra-Cold Temperatures
Gauge theories are at the heart of our modern understanding of physics, but solving their out-of-equilibrium dynamics is extremely challenging for classical computers. This difficulty is currently spurring a worldwide effort to solve gauge theories on dedicated quantum computing devices. In this webinar hosted by the Quantum Computing and Communication Technical Group, Philipp Hauke from the University of Trento will discuss recent progress towards quantum simulation of gauge theories using ultracold atoms, trapped ions, and superconducting qubits.

First, Hauke will present recent breakthrough experiments, one of which has realized a many-body gauge theory in a 71-site Hubbard model and has certified the fulfilment of Gauss’s law for the first time. Moreover, Hauke will discuss their ongoing theoretical effort to quantify and mitigate the influence of microscopic violations of the local gauge symmetry. Through these discussions, Hauke will aim at outlining a roadmap towards mature and practically relevant quantum simulation of gauge theories.

Philipp Hauke
@University of Trento
Philipp Hauke received his PhD in 2013 from ICFO – The Institute of Photonic Sciences, Castelldefels, Barcelona. Afterwards, he held positions as University Assistant at the University of Innsbruck and as group leader at Heidelberg University, funded by an ERC Starting grant. In fall 2019, he became Associate Professor at the INO-CNR BEC Center and the Physics Department of the University of Trento. His research focuses on developing the theoretical basis for novel quantum technologies. The vision is to harness the pristine control available in synthetic quantum systems such as cold atoms, trapped ions, superconducting qubits, or photonic devices for solving outstanding problems of practical relevance. Philipp Hauke’s group develops methods to characterize and measure entanglement as a quantum resource, derives algorithms to solve hard NP-complete problems through quantum annealing, and designs quantum simulations of strongly-correlated systems.
