Abstract

The authors compute the quantum complexity of cosmological density perturbations during the expansion of the Universe. Using complexity as a diagnostic the authors show that the amount of quantum chaos of the accelerating Universe is bounded. Further, they find that de Sitter space is the most chaotic cosmological background preserving the null energy condition
