Information-based approach towards a unified resource theory
A. C. S. Costa, R. M. Angelo
Resource theories play an important role in quantum information theory, as they identify resourceful states and channels that are potentially useful for the accomplishment of tasks…
Experimental demonstration of robust quantum steering
Sabine Wollmann, Roope Uola, Ana C. S. Costa
We analyse and experimentally demonstrate quantum steering using criteria based on generalised entropies and criteria with minimal assumptions based on the so-called dimension-boun…
Quantum Steering
Roope Uola, Ana C. S. Costa, H. Chau Nguyen +1
Quantum correlations between two parties are essential for the argument of Einstein, Podolsky, and Rosen in favour of the incompleteness of quantum mechanics. Schrödinger noted tha…
Entropic Steering Criteria: Applications to Bipartite and Tripartite Systems
Ana C. S. Costa, Roope Uola, Otfried Gühne
The effect of quantum steering describes a possible action at a distance via local measurements. Whereas many attempts on characterizing steerability have been pursued, answering t…
