Non-Gaussian state generation certified using the EPR-steering inequality
E. S. Gómez, G. Cañas, E. Acuña +2
Due to practical reasons, experimental and theoretical continuous-variable (CV) quantum information (QI) has been heavily based on Gaussian states. Nevertheless, many CV-QI protoco…
Quantum key distribution with untrusted detectors
P. Gonzalez, L. Rebon, T. Ferreira da Silva +6
Side-channel attacks currently constitute the main challenge for quantum key distribution (QKD) to bridge theory with practice. So far two main approaches have been introduced to a…
Defocusing microscopy with an arbitrary size for the aperture of the objective lens
Ivan F. Santos, W. A. T. Nogueira, S. Etcheverry +3
The theoretical approach to describe the defocusing microscopy technique by U. Agero et al. [Phys. Rev. E {\bf 67}, 051904 (2003)] assumes that the size of the objective lens apert…
Quantifying the non-Gaussianity of the state of spatially correlated down-converted photons
E. S. Gómez, W. A. T. Nogueira, C. H. Monken +1
The state of the spatially correlated down-converted photons is usually treated as a two-mode Gaussian entangled state. While intuitively this seems to be reasonable, it is known t…
Optimal measurement bases for Bell-tests based on the CH-inequality
G. Lima, E. B. Inostroza, R. O. Vianna +2
The Hardy test of nonlocality can be seen as a particular case of the Bell tests based on the Clauser-Horne (CH) inequality. Here we stress this connection when we analyze the rela…
Bell scenarios in which nonlocality and entanglement are inversely related
G. Vallone, G. Lima, E. S. Gómez +4
We show that for two-qubit chained Bell inequalities with an arbitrary number of measurement settings, nonlocality and entanglement are not only different properties but are invers…
