Sufficient separability criteria and linear maps
Maciej Lewenstein, Remigiusz Augusiak, Dariusz Chruściński +2
We study families of positive and completely positive maps acting on a bipartite system (with ). The maps have a property that when appl…
Self-testing protocols based on the chained Bell inequalities
Ivan Šupić, Remigiusz Augusiak, Alexia Salavrakos +1
Self testing is a device-independent technique based on non-local correlations whose aim is to certify the effective uniqueness of the quantum state and measurements needed to prod…
Unbounded randomness certification using sequences of measurements
F. J. Curchod, M. Johansson, R. Augusiak +3
Unpredictability, or randomness, of the outcomes of measurements made on an entangled state can be certified provided that the statistics violate a Bell inequality. In the standard…
Asymptotic role of entanglement in quantum metrology
Remigiusz Augusiak, Jan Kolodynski, Alexander Streltsov +3
Quantum systems allow one to sense physical parameters beyond the reach of classical statistics---with resolutions greater than , where is the number of constituent partic…
Nonlocality in many-body quantum systems detected with two-body correlators
J. Tura, R. Augusiak, A. B. Sainz +4
Contemporary understanding of correlations in quantum many-body systems and in quantum phase transitions is based to a large extent on the recent intensive studies of entanglement…
Generalized XOR games with outcomes and the task of non-local computation
Ravishankar Ramanathan, Remigiusz Augusiak, Gláucia Murta
A natural generalization of the binary XOR games to the class of XOR-d games with outcomes is studied. We propose an algebraic bound to the quantum value of these games and…
