Description
In recent years, quantum-information processing has seen rapid advances, on the level of devices as well as our theoretical understanding of quantum many-body systems. These hand us paradigmatically novel computational methods in the form of quantum simulators, quantum computers, and tensor networks. Simultaneously, fundamental questions such as about the role of entanglement in quantum many-body systems are moving into focus. Internationally, the game-changing potential of quantum technologies and quantum information theory for nuclear physics has already been recognized, and has led to strategic actions that are still lacking on a pan-European level.
Here, we outline some of the recent developments at the interface of nuclear physics and quantum technologies and how they may impact nuclear theory in the next years to come. This white paper complements the one by Lacroix et al., entitled “Quantum computing for nuclear physics". Our focus is in particular on aspects of high-energy nuclear theory, gauge theories and field theories, and quantum information approaches to physics questions as well as numerical calculations.
