Quantum Magic and Entanglement in Nuclear Many-Body Systems — •Federico Rocco¹, James W. T. Keeble¹, and Caroline Robin^{1, 2} — ¹Fakultät für Physik, Universität Bielefeld, D-33615 Bielefeld, Germany — ²GSI Helmholtzzentrum für Schwerionenforschung, Planckstraße 1, D-64291 Darmstadt, Germany

Concepts of quantum information science shed light on the complexity of quantum many-body systems, providing new insights into the structure of matter and emergence of degrees of freedom. Non-stabilizerness, or magic, is related to the amount of non-Clifford resources required to perform a quantum simulation and has emerged as a central quantity in the study of quantum complexity. Beyond that, estimates of non-local magic between different partitions of the nuclear system can uncover many-body correlations not captured by entanglement. In this talk, I will discuss investigations of magic and non-local magic based on stabilizer Rényi entropies in atomic nuclei, as well as the connection between quantum complexity, emergent collective behavior and shape deformation.

Keywords: Entanglement; Quantum Magic; Quantum Simulation
