GPU-accelerated semidefinite programming for causal games
Emanuel-Cristian Boghiu, Kyrylo Simonov
The process matrix formalism describes quantum correlations in scenarios without a fixed causal order between local laboratories. Operational signatures of such correlations can be…

Characterizing entanglement dynamics in QED scattering processes
Massimo Blasone, Silvio De Siena, Gaetano Lambiase +2
We study entanglement dynamics among helicity degrees of freedom in quantum electrodynamics (QED) scattering processes. For generic initial states, we consider scattering at fixed…

Tests of macrorealism in meson oscillation physics
Massimo Blasone, Fabrizio Illuminati, Luciano Petruzziello +2
Macrorealism formalizes the intuitive notion that at any given time the system occupies a definite state and that the evolution of the system is independent of the measurements per…
