Quantum Many-Body Dynamics and Noisy Intermediate-Scale Quantum Computers: Interconnections, Near-Term Applications, and Novel Simulation Schemes
Quantum computing is at the forefront of modern scientific research, promising to revolutionize technology by solving complex problems beyond the reach of classical computers. Currently, the field is in the era of Noisy Intermediate-Scale Quantum (NISQ) devices, which are limited by noise and decoherence. Despite these limitations, NISQ devices hold significant potential for simulating quantum many-body dynamics which is notoriously challenging with classical computers. Crucially, at least for certain problems, NISQ devices have started to challenge modern supercomputers. Over the past two decades, the properties of quantum systems out of equilibrium have experienced an upsurge of interest. Longstanding questions have received renewed attention, e.g., regarding the origin of hydrodynamic transport under unitary time evolution or the spreading of entanglement. Research on strongly disordered quantum systems has unveiled the possibility of a many-body localized (MBL) phase, where systems fail to reach thermal equilibrium under their own dynamics. Moreover, the advent of NISQ devices has fueled efforts to explore out-of-equilibrium phases of matter in monitored circuits consisting of unitary gates interspersed with random measurements. The project “MaBoQuaCo” seeks to bridge the gap between the theoretical understanding of quantum many-body dynamics and the practical capabilities of NISQ devices. It aims to deliver important breakthroughs in both areas and its overarching goal is to explore the connections between these two fields. In addition to studying fundamental aspects of out-of-equilibrium quantum dynamics, the project will explore avenues to leverage the capabilities of NISQ devices for this purpose and develop efficient algorithms and simulation techniques inspired by and tailored for NISQ hardware.

Project objective
Simulating the dynamics of quantum many-body systems is notoriously difficult as the computational requirements grow dramatically with increasing system size. While fully-fledged quantum computing may provide a means to handle this challenge, today's noisy intermediate-scale quantum (NISQ) devices are prone to errors and decoherence. This interdisciplinary project promises significant progress in the understanding of nonequilibrium quantum systems and in leveraging the capabilities of NISQ devices for this purpose. The innovative research is going to capitalize on the concept of quantum typicality to explore near-term applications of random quantum states on NISQ devices and to study the emergence of hydrodynamics in isolated quantum systems. By combining state-of-the-art theoretical and numerical approaches with simulations on available quantum hardware, important insights will furthermore be gained into the universal properties of quantum dynamics in driven-dissipative systems, in monitored circuits consisting of unitary gates and projective measurements, and in many-body localized systems coupled to a thermal bath. Tackling these key areas will provide a deeper understanding of fundamental physics and will unravel the inevitable interaction of NISQ devices with their environment. Results may open up new avenues for robust and scalable simulations on NISQ devices, which is vital as quantum technology continues to mature. Additionally, this project will deliver novel NISQ-inspired classical simulation schemes, which are memory-efficient and will pave the way to answer open questions that are challenging for other methods. Highlighting the strong synergy and profound interplay between quantum many-body dynamics and NISQ devices, this project follows Horizon Europe's strategic plan of developing key digital and emerging technologies and is in line with Europe's Quantum Flagship initiative to foster European excellence in quantum technologies.
