    "abstract": "This is a conceptual paper that re-examines the principles underlying the\napplication of renormalization theory to quantum phase transitions in the light\nof quantum information theory. We start by describing the intuitive argument\nknown as the Kadanoff ``block-spin\u0027\u0027 construction for spins fixed on a lattice\nand then outline some subsequent ideas by Wilson and White. We then reconstruct\nthese concepts for quantum phase transitions from first principles. This new\nperspective offers some very natural explanations for some features of\nrenormalization theory that had previously seemed rather mysterious, even\ncontrived. It also offers some suggestions as to how we might modify\nrenormalization methods to make them more successful. We then discuss some\npossible order parameters and a class of functionals that are analogues of the\ncorrelation length in such systems.",
