Essential entanglement for atomic and molecular physics
Malte C Tichy, Florian Mintert, Andreas Buchleitner · Journal of Physics B Atomic Molecular and Optical Physics · 2011
Entanglement is nowadays considered as a key quantity for the understanding of correlations, transport properties, and phase transitions in composite quantum systems, and thus receives interest beyond the engineered applications in the focus of quantum information science. We review recent experimental and theoretical progress in the study of quantum correlations under that wider perspective, with an emphasis on rigorous definitions of the entanglement of identical particles, and on entanglement studies in atoms and molecules.
