Measuring CP violation using quantum state tomography
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
We investigate direct CP violation in neutral meson decays by reconstructing the associated density matrices and measuring their difference using the trace distance. Our results co…
Quantum pions
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
We show that two- and three-pion states produced in the decay of neutral kaons are contextual, entangled, and Bell nonlocal in isospin space. By reinterpreting the experimental val…
Local vs. nonlocal entanglement in top-quark pairs at the LHC
M. Fabbrichesi, R. Floreanini, L. Marzola
We show that the entanglement observed in top-antitop quark spin states at the LHC is local in the energy region close to the production threshold. In contrast, nonlocal entangleme…
Tests of quantum contextuality in particle physics
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Quantum contextuality refers to the impossibility of assigning a predefined, intrinsic value to a physical property of a system independently of the context in which the property i…
Quantum contextuality of spin-1 massive particles
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Contextuality is a fundamental property of quantum mechanics. Contrary to entanglement, which can only exist in composite systems, contextuality is also present for single entities…
About testing Bell locality at colliders
M. Fabbrichesi, R. Floreanini, L. Marzola
High-energy colliders enable the testing of quantum mechanics at its most fundamental level, in the presence of strong and electroweak interactions, with systems that consist of qu…
