Detecting entanglement from macroscopic measurements of the electric field and its fluctuations
Pedro Rosario, Alan C. Santos, Nicola Piovella +3
To address the outstanding task of detecting entanglement in large quantum systems, entanglement witnesses have emerged, addressing the separable nature of a state. Yet optimizing…

Quantum steering ellipsoids and quantum obesity in critical systems
Pedro Rosario, Alan C. Santos
Quantum obesity (QO) is new function used to quantify quantum correlations beyond entanglement, which also works as a witness for entanglement. Thanks to its analyticity for arbitr…

Swapping of quantum correlations and the role of local filtering operations
Pedro Rosario, Andrés F. Ducuara, Cristian E. Susa
We address the swapping of various quantum correlation measures including: Bell-nonlocality, EPR-steering, usefulness for teleportation, entanglement, quantum obesity, as well as t…
