Quantum discord for two-qubit states
Quantum discord, a kind of quantum correlation, is defined as the difference between
quantum mutual information and classical correlation in a bipartite system. In general, this …

Shareability of steering in 2-producible states
QC Song, TJ Baker, HM Wiseman - Physical Review A, 2023 - APS
Quantum steering is the phenomenon whereby one party (Alice) proves entanglement by
“steering” the system of another party (Bob) into distinct ensembles of states, by performing …
