Measurements and Information in Spin Foam Models [PDF]
J. Manuel Garcia-IslasWe present a problem relating measurements and information theory in spin foam models. In the three dimensional case of quantum gravity we can compute probabilities of spin network graphs and study the behaviour of the Shannon entropy associated to the corresponding information. We present a general definition, compute the Shannon entropy of some examples, and find some interesting inequalities.View original: http://arxiv.org/abs/1206.2107
