CA24109 - Many-body Open Quantum Systems (QOpen)

QOpen aims to substantially boost understanding of complex many-body quantum systems that interact with their environment, leading to decoherence and dissipation. While these effects pose challenges for observing quantum coherent dynamics and have often impeded the development of quantum technologies, they can also be leveraged, e.g. for dissipative quantum error correction. Moreover, exploring non-equilibrium open quantum systems offers the opportunity to discover states of matter that are not achievable in thermal equilibrium. 

The Action aims to address key challenges, such as understanding integrable and chaotic dissipative dynamics, thermalization, and the emergence of new, non-equilibrium quantum states of matter. It seeks to advance characterization and control methods for open quantum platforms and promote the development of novel numerical and analytical approaches for modeling these systems. A significant focus is placed on leveraging noisy intermediate-scale quantum (NISQ) devices, which are inherently dissipative many-body platforms, for these investigations. 

QOpen establishes a collaborative European framework, bringing together experts from various disciplines and regions, with particular attention to inclusiveness target countries (ITCs). The Action highlights capacity-building through training and mentoring young researchers, engaging with the quantum industry, and promoting interdisciplinary and international collaborations. It aims to create a sustainable, inclusive research network to fuel future research and innovation in the field. While prioritizing fundamental research, the Action engages with the quantum industry sector and aligns with Europe’s goals of maintaining leadership in quantum technologies.
