Can quantum technologies solve fundamental physics problems?

The central research topic of our group is quantum simulation — the use of controlled quantum systems to study complex quantum phenomena beyond the reach of traditional methods.

We first identify target models, often quantum field theories motivated by high-energy or condensed matter physics. These models are subsequently adapted and reformulated in a way amenable to the capabilities of analog quantum simulators or digital quantum computers, and in this context we develop quantum algorithms that aim to solve fundamental physics questions. Throughout our work we employ a variety of analytical and numerical tools from quantum information theory, notably tensor network methods, while staying in close contact with experimental colleagues who build the devices that can implement our theoretical proposals.
