WebNov 9, 2016 · Nonlocality is one of the most startling predictions of quantum mechanics. It allows two distant observers to obtain experimental statistics that cannot be described by any classical common cause (given a few reasonable physical assumptions) [1, 2].Recently confirmed in loophole-free experiments [3–5] nonlocality has been proven to be useful … WebIn particular, a tripartite system HA ⊗ HB ⊗ HC, where Hj is a finite dimensional complex Hilbert space for j = A, B, C, is considered and a set of invariants under local transformations is introduced, which is complete for the set of states whose partial trace with respect to HA belongs to the class of generic mixed states.
