The original research publication[1] only seems to determine the possibility of complete QMC simulations on classical computational resources. While this shows we can't fully simulate portions of certain quantum systems on classical resources, it doesn't necessarily prove that a simulation of our universe is impossible, given the possibility of different physics in some "meta universe." 1: http://advances.sciencemag.org/content/3/9/e1701758.full http://advances.sciencemag.org/content/3/9/e1701758.full
