Recently, the study of gauge theories has been recognized as an unexpected field of application of quantum technologies. Gauge theories describe some of the most fundamental and intriguing processes occurring in Nature, ranging from the interaction of elementary high energy particles – described by the Standard Model – to condensed matter systems displaying frustration or topological order.
Despite being at the heart of our understanding of many fundamental processes, these systems elude most of our investigative approaches in the non-perturbative regime, whenever real-time dynamics, finite fermionic densities and other problems with complex action are involved and the infamous sign problem hinders the effectiveness of Monte Carlo methods.
Thus, developing novel approaches without such limitations will pave the way to unprecedented research possibilities and exciting developments.
This is the project’s goal: to develop a new quantum-based sign-problem-free technology to simulate strongly correlated many-body quantum systems with Abelian and non-Abelian dynamical gauge degrees of freedom and to apply them to the study of lower dimensional gauge theories, ultimately and in the very long run aiming at Quantum Chromodynamics.
This interdisciplinary project can be developed only within a collaborative effort of different groups as it will exploit knowledge from experimental and theoretical branches of quantum optics; atomic, molecular and optical physics; quantum information science; high energy physics and condensed matter.
The results of this project will serve as benchmarks for the first generation of quantum simulators and will have far reaching consequences in different fundamental and applied fields of science ranging from materials science, quantum chemistry to astrophysics.
