Reformulating noncontextuality inequalities in an operational approach
Zhen-Peng Xu, Debashis Saha, Hong-Yi Su +2
A new theory-independent noncontextuality inequality is presented [Phys. Rev. Lett. 115, 110403 (2015)] based on Kochen-Specker (KS) set without imposing the assumption of determin…
Optimal GHZ Paradox for Three Qubits
Changliang Ren, Hong-Yi Su, Zhen-Peng Xu +2
Quatum nonlocality as a valuable resource is of vital importance in quantum information processing. The characterization of the resource has been extensively investigated mainly fo…
Sharp Contradiction for Local-Hidden-State Model in Quantum Steering
Jing-Ling Chen, Hong-Yi Su, Zhen-Peng Xu +1
In quantum theory, no-go theorems are important as they rule out the existence of a particular physical model under consideration. For instance, the Greenberger-Horne-Zeilinger (GH…
Quantum contextuality of a qutrit state
Zhen-Peng Xu, Hong-Yi Su, Jing-Ling Chen
We present a study of quantum contextuality of three-dimensional mixed states for the Klyachko-Can-Binicioğlu-Shumovsky (KCBS) and the Kurzyński-Kaszlikowski (KK) noncontextuality…
State-independent contextuality sets for a qutrit
Zhen-Peng Xu, Jing-Ling Chen, Hong-Yi Su
We present a generalized set of complex rays for a qutrit in terms of parameter , a -th root of unity. Remarkably, when , the set reduces to two well known s…
