Incompatible quantum measurements admitting a local hidden variable model
Marco Túlio Quintino, Joseph Bowles, Flavien Hirsch +1
The observation of quantum nonlocality, i.e. quantum correlations violating a Bell inequality, implies the use of incompatible local quantum measurements. Here we consider the conv…
Sufficient criterion for guaranteeing that a two-qubit state is unsteerable
Joseph Bowles, Flavien Hirsch, Marco Túlio Quintino +1
Quantum steering can be detected via the violation of steering inequalities, which provide sufficient conditions for the steerability of quantum states. Here we discuss the convers…
Inequivalence of entanglement, steering, and Bell nonlocality for general measurements
Marco Túlio Quintino, Tamás Vértesi, Daniel Cavalcanti +4
Einstein-Podolsky-Rosen steering is a form of inseparability in quantum theory commonly acknowledged to be intermediate between entanglement and Bell nonlocality. However, this sta…
