    "abstract": "Entanglement is one of the pillars of quantum mechanics and quantum\ninformation processing, and as a result the quantumness of nonentangled states\nhas typically been overlooked and unrecognized. We give a robust definition for\nthe classicality versus quantumness of a single multipartite quantum state, a\nset of states, and a protocol using quantum states. We show a variety of\nnonentangled (separable) states that exhibit interesting quantum properties,\nand we explore the ``zoo\u0027\u0027 of separable states; several interesting subclasses\nare defined based on their diagonalizing bases, and their non-classical\nbehavior is investigated.",
