Quantum Technologies For LAttice Gauge theories (QTFLAG)

In the past decades, quantum technologies have been fast developing from proof-of-principle experiments to ready-to-the-market solutions. Applications in this far-reaching field include for examples quantum sensors for high precision measurements, secure communication systems and quantum simulations. Recently, the study of gauge theories has been recognised 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 particles described by the Standard Model to condensed matter models displaying exotic quantum behaviour such as topological order. Despite being at the heart of our understanding of these fundamental processes, these theories elude most of our investigative approaches whenever dynamics and finite fermionic densities 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. This is the projects goal: to develop a new quantum-based sign-problem-free technology to simulate strongly correlated many-body quantum systems and to apply them to the study of gauge theories, ultimately aiming at Quantum Chromodynamics. The results of this project will bring the first generation of quantum simulators to live and will have far reaching consequences in different fundamental and applied fields of science ranging from materials science, quantum chemistry to astrophysics.
