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…
Hierarchy of Steering Criteria Based on Moments for All Bipartite Quantum Systems
Ioannis Kogias, Paul Skrzypczyk, Daniel Cavalcanti +2
Einstein-Podolsky-Rosen steering is a manifestation of quantum correlations exhibited by quantum systems, that allows for entanglement certification when one of the subsystems is n…
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…
A new property of the Lovász number and duality relations between graph parameters
Antonio Acín, Runyao Duan, David E. Roberson +2
We show that for any graph , by considering "activation" through the strong product with another graph , the relation between the independence number…
Most energetic passive states
Martí Perarnau-Llobet, Karen V. Hovhannisyan, Marcus Huber +3
Passive states are defined as those states that do not allow for work extraction in a cyclic (unitary) process. Within the set of passive states, thermal states are the most stable…
