Characterizing nonlocality of pure symmetric three-qubit states
K. Anjali, Akshata Shenoy Hejamadi, H. S. Karthik +3
We explore nonlocality of three-qubit pure symmetric states shared between Alice, Bob and Charlie using the Clauser-Horne-Shimony-Holt (CHSH) inequality. We make use of the elegant…

Algebraic maximum violation of the Leggett-Garg inequality in a two-level system under PT symmetric dynamics
H. S. Karthik, Akshata Shenoy Hejamadi, A. R. Usha Devi
We investigate the three-term Leggett-Garg inequality (LGI) for a two-level quantum system undergoing parity-time (PT ) symmetric dynamics governed by a non-Hermitian Hamiltonian,…
