Two papers from the quantum-information line were published in 2026: Cat states and violation of the Bell-CHSH inequality in relativistic Quantum Field Theory (Phys. Rev. D 113, 065008, arXiv:2601.05216) and Bell-CHSH inequality and unitary transformations in Quantum Field Theory (Eur. Phys. J. C 86, 230, arXiv:2412.03840).
