Geometric measure for two-qubit CS-states: an exactly solvable model

24 Oct 2018  ·  Masoud Abolfathiyar, Sina Entekhabi ·

Newly, during an analytical calculation M. A. Yurischev [arXiv: 1302.5239 (2013)] prove that quantum discord (or entanglement) remains unchangeable for any centrosymmetric (CS) states that are converted to their corresponding mode X. In this paper, in addition to the above calculations, the conditions which geometric measure remains constant are presented... This work will be completed with discussion about two physical examples. read more
