J Gao, L Santos, G Krishna, ZS Xu, A Iovan… - Nano Letters, 2023 - ACS Publications
Quantum physics phenomena, entanglement and coherence, are crucial for quantum
information protocols, but understanding these in systems with more than two parts is …

[HTML][HTML] Remarks about Bell-nonclassicality of a single photon

T Das, M Karczewski, A Mandarino, M Markiewicz… - Physics Letters A, 2022 - Elsevier
We discuss the interferometric scheme put forward by Tan, Walls, and Collett (TWC) that
claims to reveal Bell non-classicality of a single photon. We show that the violation of local …

Revisited aspects of the local set in CHSH Bell scenario

N Gigena, G Scala, A Mandarino - International Journal of Quantum …, 2023 - World Scientific
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 …

Comment on 'Single particle nonlocality with completely independent reference states'

T Das, M Karczewski, A Mandarino… - New Journal of …, 2022 - iopscience.iop.org
We comment on the purported violation of local realism, by a single photon induced
correlations between homodyne detectors, which one can find in:(2008) New J. Phys. 10 …

Bosonic fields in states with undefined particle numbers possess detectable non-contextuality features, plus more

K Schlichtholz, A Mandarino… - New Journal of …, 2022 - iopscience.iop.org
The paradoxical features of quantum theory are usually formulated for fixed number of
particles. While one can now find a formulation of Bell's theorem for quantum fields, a …

On the Fidelity Robustness of CHSH–Bell Inequality via Filtered Random States

A Mandarino, G Scala - Entropy, 2023 - mdpi.com
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 …

CHSH Bell tests for optical hybrid entanglement

M Moradi, JCL Carreño, A Buraczewski… - New Journal of …, 2024 - iopscience.iop.org
Optical hybrid entanglement can be created between two qubits, one encoded in a single
photon and another one in coherent states with opposite phases. It opens the path to a …

Insights into Quantum Contextuality and Bell Nonclassicality: a Study on Random Pure Two-Qubit Systems

G Scala, A Mandarino - International Journal of Theoretical Physics, 2024 - Springer
We explore the relationship between Kochen-Specker quantum contextuality and Bell-
nonclassicality for ensembles of two-qubit pure states. We present a comparative analysis …
