This workshop will be centered around the topic of entanglement in many-body systems relevant for and connected to NP. The goal is to advance exchanges of ideas and techniques between NP and other fields of many-body physics such as condensed matter, quantum chemistry or quantum field theories. These areas are already well advanced in the characterization and use of entanglement for the description of many-body systems, and in the development of experimental techniques for producing and detecting entangled states. The knowledge acquired in these fields can guide progress in the development of entanglement-driven methods for classical and quantum simulations of nuclei, and in the identification of experiments probing entanglement in nuclear systems. Vice versa, specificities of many-body NP techniques can potentially be useful for other fields, and QIS in general. The workshop will explore these different aspects.
