Friday's seminar at 11:00 in HIT K52

Hi all, Happy New Year! We start the year with a talk from Andrea Di Biagio titled “The simple reason classical gravity can entangle: a tale of two localities”. See below for the abstract. The talk will take place on Friday at 11:00 in HIT K52. Best, Ladina %%%%%%%%% Title: The simple reason classical gravity can entangle: a tale of two localities Abstract: Since the Bose et al. and Marletto and Vedral papers, more and more papers have appeared claiming that theories with a classical gravitational field do lead to gravity-induced entanglement (GIE), seemingly contradicting several theory-independent claims that local interactions with a classical system cannot lead to entanglement, both in quantum and post-quantum theory. After a brief overview of the latest such example (the Nature paper by Aziz and Howl), I will analyse the statement of the GIE no-go theorems. These are often presented as a contradiction between entanglement generation, locality of interactions, and classicality of the gravitational field. However, the information-theoretic assumption of locality they employ (based on subsystem decomposition) is distinct from the spacetime notions of locality natural to field theories like gravity. The unclear relation between these two kinds of locality undermines the theory-independent applicability of the no-go theorems to extant gravitational theories.
