An axiomatic avenue to AdS/CFT
Speaker(s): Cédric Bény
Abstract: I will review a recent proposal for a top-down approach to AdS/CFT by A. Schwarz, which has the advantage of requiring few assumptions or extraneous knowledge, and may be of benefit to information theorists interested by the connections with tensor networks. I will also discuss ways to extend this ... read more

Tangent field theory
Speaker(s): Cédric Bény
Abstract: The modern understanding of quantum field theory underlines its effective nature: it describes only those properties of a system relevant above a certain scale. A detailed understanding of the nature of the neglected information is essential for a full application of quantum information-theoretic to... read more

Causal Structure of MERA
Speaker(s): Cédric Bény
Abstract: The multiscale entanglement renormalization ansatz can be reformulated in terms of a causality constraint on discrete quantum dynamics. This causal structure is that of de Sitter space with a flat spacelike boundary, where the volume of a spacetime region corresponds to the number of variational par... read more

Unsharp pointer observables and the structure of decoherence
Speaker(s): Cédric Bény
Abstract: Decoherence attempts to explain the emergent classical behaviour of a quantum system interacting with its quantum environment. In order to formalize this mechanism we introduce the idea that the information preserved in an open quantum evolution (or channel) can be characterized in terms of obse... read more
