Abstract
In Phys. Lett. A 166, 293 (1992), Popescu and Rohrlich characterized nonlocality of pure -partite entangled systems by studying bipartite violation of local realism when number of parties perform projective measurements on their particles. A pertinent question in this scenario is whether similar characterization is possible for -partite mixed entangled states also. In the present work we have followed an analogous approach so as to explore whether given a tripartite mixed entangled state the conditional bipartite states obtained by performing projective measurement on the third party demonstrate a weaker form of nonlocality, quantum steering. We also compare this phenomenon of conditional steering with existing notions of tripartite correlations.
