Abstract

One significant feature of quantum theory is the existence of non-local quantum correlations which have no classical counterpart. There are various measures quantifying quantum correlations from different view points. Here, we present some recent developments about the quantum correlation measures known as measurement-induced nonlocality, in the sense that quantum measurement may destroy the quantum correlations for quantum states resulting in measures of nonlocality. Quantum correlations remain invariant under local unitary operations, they may decrease under general local operations, however, sometimes they can also show increasing for some local operations. We will review the properties of quantum correlations under local operations.
