    "abstract": "Quantum entanglement entropy has a geometric character. This is illustrated\nby the interpretation of Rindler space or black hole entropy as entanglement\nentropy. In general, one can define a \"geometric entropy\", associated with an\nevent horizon as a boundary that concentrates a large number of quantum states.\nThis allows one to connect with the \"density matrix renormalization group\" and\nto unveil its connection with the theory of quantum information. This\nrenormalization group has been introduced in condensed matter physics in a\nheuristic manner, but it can be conceived as a method of compression of quantum\ninformation in the presence of a horizon. We propose generalizations to\nproblems of interest in cosmology.",
