Entanglement and non-separability of momenta and coordinates at colliders
Marco Fabbrichesi, Roberto Floreanini, Luca Marzola
We explore the possibility of testing in collider experiments whether phase-space variables are separable. We first study phase-space non-separability by means of EPR-like correlat…
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…
Bell inequality is violated in charmonium decays
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
The experimental data on the helicity amplitudes of charmonium decays allow us to measure entanglement in final state spin correlations and test possible violations of the Bell ine…
