The statistical measures of complexity defined by Lopez-Ruiz, Mancini, andCalbet (LMC) and Shiner, Davison and Landsberg (SDL) are calculated asfunctions of the number of particles for four quantum many-body systems, i.e.atoms, nuclei, atomic clusters, and correlated atoms in a trap (bosons). A pairof order and disorder strengths, evaluated for each system, can serve as a Pairof Order-Disorder Indices (PODI), characterizing quantitatively order versusdisorder in any quantum system. According to the above classification, weassign to bosons the complexity character of disorder, to atoms the characterof order, while nuclei and atomic clusters are (less) disordered and liebetween them. This criterion can be used to estimate the relative contributionof order and disorder to complexity for other more complicated quantum systemsas well and even classical ones, if one is able to describe themprobabilistically. We also address the issue, whether those systems can grow incomplexity as the number of particles increases. Our comparative studyindicates that atoms are the only quantum system out of four, which is ordered,with the ability to self-organize. We conjecture that this is aninformation-theoretic reason that atoms are suitable as building blocks oflarger structures of biological interest i.e. molecules and macromolecules.This is in the spirit of Wheeler's "it from bit" quote, the project to presenteverything about the Universe in terms of information theory.
