State updates and useful qubits in relativistic quantum information
José Polo-Gómez, T. Rick Perche, Eduardo MartÃn-MartÃnez
We address the longstanding challenge of consistently updating quantum states after selective measurements in a relativistic spacetime. Standard updates along the future lightcones…

The multimode nature of spacetime entanglement in QFT
Ivan Agullo, Béatrice Bonga, Eduardo MartÃn-MartÃnez +5
We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…
