Optimality of generalized Choi maps in
Giovanni Scala, Anindita Bera, Gniewomir Sarbicki +1
A family of linear positive maps in the algebra of complex matrices proposed recently in Bera et al. arXiv:2212.03807 is further analyzed. It provides a generalization…
On the Fidelity Robustness of CHSH--Bell Inequality via Filtered Random States
Antonio Mandarino, Giovanni Scala
The theorem developed by John Bell constituted the starting point of a revolution that translated a philosophical question about the nature of reality into the broad and intense fi…
Information theoretical perspective on the method of Entanglement Witnesses
Paulo J. Cavalcanti, Giovanni Scala, Antonio Mandarino +1
We frame entanglement detection as a problem of random variable inference to introduce a quantitative method to measure and understand whether entanglement witnesses lead to an eff…
Advantages of quantum communication revealed by the reexamination of hyperbit theory limitations
Giovanni Scala, Seyed Arash Ghoreishi, Marcin Pawłowski
Pawłowski and Winter's hyperbit theory, proposed in 2012, presented itself as an alternative to quantum theory, suggesting novel ways of redefining entanglement and classical commu…
Revisited aspects of the local set in CHSH Bell scenario
Nicolas Gigena, Giovanni Scala, Antonio Mandarino
The Bell inequalities stand at the cornerstone of the developments of quantum theory on both the foundational and applied side. The discussion started as a way to test whether the…
Generalizing Choi map in beyond circulant scenario
Anindita Bera, Giovanni Scala, Gniewomir Sarbicki +1
We present a generalization of the family of linear positive maps in proposed thirty years ago by Cho et al. (Linear Algebra Appl. , 213 (1992)) as a generalizatio…
Aspects of the phenomenology of interference that are genuinely nonclassical
Lorenzo Catani, Matthew Leifer, Giovanni Scala +2
Interference phenomena are often claimed to resist classical explanation. However, such claims are undermined by the fact that the specific aspects of the phenomenology upon which…
What is nonclassical about uncertainty relations?
Lorenzo Catani, Matthew Leifer, Giovanni Scala +2
Uncertainty relations express limits on the extent to which the outcomes of distinct measurements on a single state can be made jointly predictable. The existence of nontrivial unc…
Comparative analysis of signal-to-noise ratio in correlation plenoptic imaging architectures
Gianlorenzo Massaro, Giovanni Scala, Milena D'Angelo +1
Correlation plenoptic imaging (CPI) is a scanning-free diffraction-limited 3D optical imaging technique exploiting the peculiar properties of correlated light sources. CPI has been…
Avenues to generalising Bell inequalities
Marcin Karczewski, Giovanni Scala, Antonio Mandarino +2
Characterizing the set of all Bell inequalities is a notably hard task. An insightful method of solving it in case of Bell correlation inequalities for scenarios with two dichotomi…
Beyond the Rabi model: light interactions with polar atomic systems in a cavity
Giovanni Scala, Karolina Słowik, Paolo Facchi +2
The Rabi Hamiltonian, describing the interaction between a two-level atomic system and a single cavity mode of the electromagnetic field, is one of the fundamental models in quantu…
Detection power of separability criteria based on a correlation tensor: a case study
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
Detection power of separability criteria based on a correlation tensor is tested within a family of generalized isotropic state in . For all these c…
Distance sensing emerging from second-order interference of thermal light
Francesco V. Pepe, Gabriele Chilleri, Giovanni Scala +3
We introduce and describe a technique for distance sensing, based on second-order interferometry of thermal light. The method is based on measuring correlation between intensity fl…
Spontaneous emission in dispersive media without point-dipole approximation
Giovanni Scala, Francesco V. Pepe, Paolo Facchi +2
We study a two-level quantum system embedded in a dispersive environment and coupled with the electromagnetic field. We expand the theory of light-matter interactions to include th…
Enhanced realignment criterion vs. linear entanglement witnesses
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
It is shown that the enhanced (nonlinear) realignment criterion is equivalent to the family of linear criteria based on correlation tensor. These criteria generalize the original (…
A family of multipartite separability criteria based on correlation tensor
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
A family of separability criteria based on correlation matrix (tensor) is provided. Interestingly, it unifies several criteria known before like e.g. CCNR or realignment criterion,…
Signal-to-noise properties of correlation plenoptic imaging with chaotic light
Giovanni Scala, Milena D'Angelo, Augusto Garuccio +2
Correlation Plenoptic Imaging (CPI) is a novel imaging technique, that exploits the correlations between the intensity fluctuations of light to perform the typical tasks of plenopt…
