Abstract:
Gauge theories are ubiquitous in fundamental physics with applications ranging from high-energy particle physics over emergent phenomena in condensed matter to quantum information science and technology. Since several regimes of interest have remained inaccessible to classical simulations, they constitute an ideal target for quantum simulations.
In this talk, I will present our progress towards the quantum simulation of lattice gauge theories (LGTs). After highlighting key challenges that are unique to LGTs, I will review the current state-of-the-art, and then discuss outstanding open problems. Our proposed solutions involve specialised quantum hardware [1] to run digital quantum algorithms [2] that are tailored to the requirements of LGTs. At the same time, existing hardware already allows us to study phenomenological aspects of LGTs, such as the dynamics of string-breaking, as demonstrated by recent results using an analog Rydberg quantum simulator [3].

Event Details & Abstracts
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
