Hi all,

Tomorrow Michał Bączyk will tell us about his master's thesis on "Black Hole Holographic Models in the framework of Gaussian Quantum Information", supervised partly by Mischa. See below for the abstract. We'll start at 2pm on zoom: https://ethz.zoom.us/j/362994444.

Best,

Title: Black Hole Holographic Models in the framework of Gaussian Quantum Information

Abstract: In this work, we make the first step towards introducing the operational quantum information notions into the framework of Conformal Field Theories and AdS/CFT correspondence. We provide an original toolkit for investigating the action of Bosonic Gaussian channels on the QFTs incorporated into the language of Gaussian Quantum Information. Specifically, we study the quench protocol dynamics for the case of vacuum state of 1D harmonic chain system and the TFD state. These are Gaussian states that have meaningful dual descriptions in the language of AdS/CFT correspondence. To evaluate the character of the free and interrupted by channels evolution we calculate numerically for the systems of interest quantum entropies and fidelities all using recent advances in the Gaussian Quantum Information.
