Self-testing with dishonest parties and device-independent entanglement certification in quantum networks
Gláucia Murta, Flavio Baccari
Here we consider the task of device-independent certification of the quantum state distributed in a network when some of the nodes in this network may collude and act dishonestly.…
On the tightness of correlation inequalities with no quantum violation
Ravishankar Ramanathan, Marco Túlio Quintino, Ana Belén Sainz +2
We study the faces of the set of quantum correlations, i.e., the Bell and noncontextuality inequalities without any quantum violation. First, we investigate the question whether ev…
Bounds on quantum nonlocality via partial transposition
Karol Horodecki, Gláucia Murta
We explore the link between two concepts: the level of violation of a Bell inequality by a quantum state and discrimination between two states by means of restricted classes of ope…
Characterising the Performance of XOR Games and the Shannon Capacity of Graphs
Ravishankar Ramanathan, Alastair Kay, Gláucia Murta +1
In this paper we give a set of necessary and sufficient conditions such that quantum players of a two-party {\sc xor} game cannot perform any better than classical players. With an…
