Uncertainty Relation Based on Skew Information with Quantum Memory

Uncertainty Relation Based on Skew Information with Quantum Memory

We present a new uncertainty relation by defining a measure of uncertainty based on skew information. For bipartite systems, we establish uncertainty relations with the existence of a quantum memory. A general relation between quantum correlations and tight bounds of uncertainty has been presented.
