Monogamy Inequality in Terms of Higher Powers of a Correlation Measure: An Analysis

March 10, 2021 Physical Science 0

We start with the fundamental concepts of quantum correlations’ restricted shareability, the so-called monogamous existence of quantum states, and how this property is manifested through a monogamy inequality. Not all quantum correlation tests are appropriate for highlighting the limited shareability of correlations in a quantum state. Although measures of bipartite correlations such as concurrence and quantum discord do not satisfy monogamy inequality for all categories of correlated data, they do not satisfy monogamy inequality for all categories of correlated data. The second powers of quantum states are discovered to do. It has also been proposed that by considering positive integral powers of any quantum correlation measure, all multiparty quantum states can be rendered monogamous (Ann. Phys. 348, 297 (2014)). We focus on this claim and investigate whether satisfying monogamy inequality in terms of higher correlation measure powers implies reduced correlation shareability.
