Graphical Non-contextual Inequalities for Qutrit Systems
Weidong Tang, Sixia Yu
One of the interesting topics in quantum contextuality is the construction for various non-contextual inequalities. By introducing a new structure called hyper-graph, we present a…

Construction of State-independent Proofs for Quantum Contextuality
Weidong Tang, Sixia Yu
Since the enlightening proofs of quantum contextuality first established by Kochen and Specker, and also by Bell, various simplified proofs have been constructed to exclude the non…

Theory-Independent Measure of Coherence
Liang-Liang Sun, Fei-Lei Xiong, Sixia Yu +1
We provide a theory independent framework to quantify coherence. In comparison with Bell's theory independent approach to quantum nonlocality, we characterize a general coherence p…
