Characterizing nonlocality of pure symmetric three-qubit states

We explore nonlocality of three-qubit pure symmetric states shared between Alice, Bob and Charlie using the Clauser-Horne-Shimony-Holt (CHSH) inequality. make use elegant parametrization in canonical form these states, proposed by Meill Meyer (Phys. Rev. A, 96, 062310 (2017)) based on Majorana geometric representation. The reduced two-qubit extracted from an arbitrary entangled state do not violate CHSH inequality hence they are CHSH-local. However, when Alice perform a test, after conditioning over measurement results Charlie, is revealed. have also shown that two different families consisting three distinct spinors (qubits) respectively, can be distinguished strength violation conditional test. Furthermore, we identify six 46 classes tight Bell inequalities three-party, two-setting, two-outcome i.e., (3,2,2) scenario A 94, 062121 (2016)). Among inequivalent only belonging to spinor class show maximum violations inequalities.
