Abstract:

Entanglement is considered the most characteristic trait of quantum mechanics. Nonetheless, almost all states---including unentangled ones---of bi-and multi-partite systems exhibit some quantum features related to correlations. Such "general quantumness of correlations" has attracted a lot of attention, but has also generated discord about its role and significance in quantum information processing. In this talk we will argue that focusing on the general quantumness of correlations may provide some insight about three fundamental tasks: (1) cloning/broadcasting; (2) entanglement distribution; (3) quantum data hiding.
