We would like to thank Robert B Mann and Tim Ralph for their kind invitation to contribute to the Focus issue of Classical and Quantum Gravity on Relativistic Quantum Information. This work was supported by the Spanish MICINN/MINECO Projects FIS2011-29287, FIS2008-06078-C03-03, FIS2011-30145-C03-02, the CAM research consortium QUITEMAD S2009/ESP-1594 and the Consolider-Ingenio 2010 Program CPAN (CSD2007-00042).We analyse the evolution of the entanglement of a non-trivial initial quantum field state (which, for simplicity, has been taken to be a bipartite state made out of vacuum and the first excited state) when it undergoes a gravitational collapse. We carry out this analysis by generalizing the tools developed to study entanglement behaviour in stationary scenarios and making them suitable to deal with dynamical spacetimes. We also discuss what kind of problems can be tackled using the formalism spelled out here, as well as single out future avenues of research.engjournal articlehttp://dx.doi.org/10.1088/0264-9381/29/22/224006http://arxiv.org/open access51-73Astronomy & astrophysicsPhysicsmultidisciplinaryparticles & fieldsFísica-Modelos matemáticosFísica matemática
