Quantumness of Product States
Jing-Ling Chen, Hong-Yi Su, Chunfeng Wu +1
Product states do not violate Bell inequalities. In this work, we investigate the quantumness of product states by violating a certain classical algebraic models. Thus even for pro…
All-Versus-Nothing Proof of Einstein-Podolsky-Rosen Steering
Jing-Ling Chen, Xiang-Jun Ye, Chunfeng Wu +4
Einstein-Podolsky-Rosen steering is a form of quantum nonlocality intermediate between entanglement and Bell nonlocality. Although Schrödinger already mooted the idea in 1935, stee…
Einstein-Podolsky-Rosen Steering in Quantum Phase Transition
Chunfeng Wu, Jing-Ling Chen, Dong-Ling Deng +3
We investigate the Einstein-Podolsky-Rosen (EPR) steering and its criticality in quantum phase transition. It is found that the EPR steerability function of the ground state of XY…
Einstein-Podolsky-Rosen Steerability Criterion for Two-Qubit Density Matrices
Jing-Ling Chen, Hong-Yi Su, Xiang-Jun Ye +2
We propose a sufficient criterion to detect Einstein-Podolsky-Rosen steering for arbitrary two-qubit density matrix . Here are respect…
Quantum contextuality for a relativistic spin-1/2 particle
Jing-Ling Chen, Hong-Yi Su, Chunfeng Wu +4
The quantum predictions for a single nonrelativistic spin-1/2 particle can be reproduced by noncontextual hidden variables. Here we show that quantum contextuality for a relativist…
