We use entropic uncertainty relations to formulate inequalities that witness
Einstein-Podolsky-Rosen (EPR) steering correlations in diverse quantum systems.
We then use these inequalities to formulate symmetric EPR-steering inequalities
using the mutual information. We explore the differing natures of the
correlations captured by one-way and symmetric steering inequalities, and
examine the possibility of exclusive one-way steerability in two-qubit states.
Furthermore, we show that steering inequalities can be extended to generalized
positive operator valued measures (POVMs), and we also derive hybrid-steering
inequalities between alternate degrees of freedom.Comment: 10 pages, 2 figure
