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 Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
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…
The Linear Collider Facility (LCF) at CERN
H. Abramowicz, E. Adli, F. Alharthi +406
In this paper we outline a proposal for a Linear Collider Facility as the next flagship project for CERN. It offers the opportunity for a timely, cost-effective and staged construc…
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…
The trace distance between density matrices, a nifty tool in new-physics searches
Marco Fabbrichesi, Matthew Low, Luca Marzola
Quantum information methods have been brought to bear on high-energy physics, including the study of entanglement and Bell nonlocality in collider experiments. Quantum information…
