QOpen is a European research network focused on many-body quantum systems interacting with their environment. It studies decoherence and dissipation as both challenges and resources for quantum technologies and non-equilibrium states of matter. The Action connects researchers across Europe to develop new methods, explore NISQ platforms, and strengthen expertise in open quantum systems.
Four interdisciplinary Working Groups (WGs) address dissipative dynamics, non-equilibrium quantum phases, NISQ characterization and control, and modelling methods for open quantum systems.
WG1
Studies thermalization, prethermalization, classical emergence, symmetries, and slow variables in open many-body quantum dynamics.
WG2
Explores and stabilizes novel non-equilibrium quantum states and phase transitions induced by driving and environments.
WG3
Develops tools to characterize and control NISQ devices, designing algorithms that exploit dissipation constructively.
WG4
Advances analytical and numerical methods, including tensor and neural networks, for higher-dimensional open systems.
