Role of maximally entangled states in the context of linear steering inequalities

Abstract
Linear steering inequalities are useful to check whether a bipartite state is steerable when both the parties are allowed to perform dichotomic measurements on their parts. In the present study we propose the necessary and sufficient condition under which -settings linear steering inequality will be violated for any given set of spin- observables at trusted and untrusted parties' sides. The important result revealed by the present paper is that maximally entangled two-qubit states give the largest quantum violations of -settings as well as -settings linear steering inequalities attainable for any given set of spin- observables at trusted and untrusted parties' sides (if any violation exists for that given set of spin- observables).
