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…
