Holographic networks for (1+1)-dimensional de Sitter space-time

Holographic tensor networks associated to tilings of (1 + 1)-dimensional de Sitter spacetime are introduced. Basic features of these networks are discussed, compared, and contrasted with conjectured properties of quantum gravity in de Sitter spacetime. Notably, we highlight a correspondence between the quantum information capacity of the network and the cosmological constant.
