Strength of the non-locality of two-qubit entangled states and its applications

A Garg, S Adhikari - Physica Scripta, 2023 - iopscience.iop.org
Non-locality is a feature of quantum mechanics that cannot be explained by local realistic
theory. It can be detected by the violation of Bell's inequality. In this work, we have …

Characterizing Bell nonlocality and EPR steerability with quantum magic squares

XS Ma, LH Bai, ZH Guo, HX Cao - Quantum Information Processing, 2022 - Springer
By exploiting the high-dimensional probability tensor, Li and Qiao (Quantum Inf Process 20:
109, 2021) proposed quantum magic square (QMS) models to characterize the diverse …

Mathematically proving Bell nonlocality motivated by the GHZ argument

Q Zhang, Z Guo, H Cao - IEEE Access, 2021 - ieeexplore.ieee.org
Bell nonlocality of quantum states is an important resource in quantum information and then
has various applications. It is usually detected by the violation of some Bell's inequalities …

Quantum channels transforming Bell local states as unsteerable states

S Xiao, LH Bai, ZH Guo, HX Cao - Quantum Engineering, 2021 - Wiley Online Library
Motivated by the contributions [Sci. Rep. 6, 39063 (2016)] and [Phys. Rev. A 98, 052114
(2018)], we aim to establish a new method for theoretically checking Bell nonlocality of a …
