Necessary and sufficient condition for nonzero quantum discord.

Necessary and sufficient condition for nonzero quantum discord.

Quantum discord characterizes "nonclassicality" of correlations in quantum mechanics. It has been proposed as the key resource present in certain quantum communication tasks and quantum computational models without containing much entanglement. We obtain a necessary and sufficient conditio...
