Quantum entanglement and Bell inequality violation at colliders
Alan J. Barr, Marco Fabbrichesi, Roberto Floreanini +2
The study of entanglement in particle physics has been gathering pace in the past few years. It is a new field that is providing important results about the possibility of detectin…
Bell inequality is violated in decays
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
The violation of the Bell inequality is one of the hallmarks of quantum mechanics and can be used to rule out local deterministic alternative descriptions. We utilize the data anal…
Stringent bounds on and anomalous couplings with quantum tomography at the LHC
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond th…
Bell inequalities and quantum entanglement in weak gauge bosons production at the LHC and future colliders
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Quantum entanglement of weak interaction gauge bosons produced at colliders can be explored by computing the corresponding polarization density matrix. To this end, we consider the…
Constraining new physics in entangled two-qubit systems: top-quark, tau-lepton and photon pairs
Marco Fabbrichesi, Roberto Floreanini, Emidio Gabrielli
The measurement of quantum entanglement can provide a new and most sensitive probe to physics beyond the Standard Model. We use the concurrence of the top-quark pair spin states pr…
Testing Bell inequalities at the LHC with top-quark pairs
M. Fabbrichesi, R. Floreanini, G. Panizzo
Entanglement between the spins of top-quark pairs produced at a collider can be used to test a (generalized) Bell inequality at energies never explored so far. We show how the meas…
