“…Interestingly, quantum correlation has found numerous applications [3] in addition to its initial motivation in pointer states [2]. For examples, relating to the difference between quantum and classical Maxwell's demons [4], its role in open dynamics [5], the local broadcasting of the quantum correlations [6,7], the phase transitions [8], its operational meaning in state merging protocols [9,10], activating multipartite entanglement [11], creating entanglement in the measurement process [12], to be a resource in quantum state discrimination [13], entanglement distribution [14,15], remote state preparation [16], observing the operational significance of quantum correlation consumption [17], guaranteeing a minimum precision in the optimal phase estimation protocol [18], interpretation as the difference in superdense coding capacities [19], and demonstrating that quantum discord cannot be shared [20].…”
