Quantum entanglement is an essential resource in quantum information processing,which needs to be verified in many tasks such as quantum cryptography and computation. Due to imperfect detection device...

In a recent note, Cavalcanti and Scarani (CS) constructed a counter local-hidden-variable model to explain the violation of our inequalities in Phys. Rev. Lett. 105, 170404 (2010). All such models ar...

The inequalities proposed in [Phys. Rev. Lett. 105, 170404 (2010)] are not Bell's inequalities in the usual sense: there are local classical models that violate these inequalities. Thus, their violati...

We derive two classes of multi-mode Bell inequalities under local realistic assumptions, which are violated only by the entangled states negative under partial transposition in accordance with the Per...

It is generally assumed that the violation of a Bell inequality by postselected events cannot be used for loophole-free tests of quantum nonlocality. We show that this is not the case if the postselec...
