Objectif
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.
