Optical nonclassicality test based on third-order intensity correlations
L. Rigovacca, W. S. Kolthammer, C. Di Franco +1
We develop a nonclassicality criterion for the interference of three delayed, but otherwise identical, light fields in a three-mode Bell interferometer. We do so by comparing the p…
Versatile relative entropy bounds for quantum networks
Luca Rigovacca, Go Kato, Stefan Bäuml +3
We provide a versatile upper bound on the number of maximally entangled qubits, or private bits, shared by two parties via a generic adaptive communication protocol over a quantum…
Versatile Gaussian probes for squeezing estimation
Luca Rigovacca, Alessandro Farace, Leonardo A. M. Souza +3
We consider an instance of black-box quantum metrology in the Gaussian framework, where we aim to estimate the amount of squeezing applied on an input probe, without previous knowl…
NonClassicality Criteria in Multiport Interferometry
Luca Rigovacca, Carlo Di Franco, Benjamin J. Metcalf +2
Interference lies at the heart of the behavior of classical and quantum light. It is thus crucial to understand the boundaries between which interference patterns can be explained…
Gaussian Discriminating Strength
Luca Rigovacca, Alessandro Farace, Antonella De Pasquale +1
We present a quantifier of non-classical correlations for bipartite, multi-mode Gaussian states. It is derived from the Discriminating Strength measure, introduced for finite dimen…
Two-walker discrete-time quantum walks on the line with percolation
Luca Rigovacca, Carlo Di Franco
One goal in the quantum-walk research is the exploitation of the intrinsic quantum nature of multiple walkers, in order to achieve the full computational power of the model. Here w…
Discriminating Strength: a bona fide measure of non-classical correlations
A. Farace, A. De Pasquale, L. Rigovacca +1
A new measure of non-classical correlations is introduced and characterized. It tests the ability of using a state ρ of a composite system AB as a probe for a quantum illumination…
