And if that is the case, can an infinite amount of it be created? Does this mean that the potential energy or the energy that can potentially be created is infinite?

    $\begingroup$ And Why don't virtual particles violate conservation of mass/energy? $\endgroup$ – Conifold Nov 22 '16 at 22:49
  • $\begingroup$ I think the OP asks for the reasons of the (im)possibility of some similar thing like a Maxwell-demon, but with quantum fluctuations (and not with thermical fluctuations). The dupe candidates, although they are similar questions, don't point into this direction and also not their answers. Thus, I vote for "leave open". $\endgroup$ – peterh Nov 22 '16 at 22:56
  • $\begingroup$ please see my answer here physics.stackexchange.com/questions/185110/… . A virtual particle can only exist as a mathematical expression under an intergral, in interactions with real particles, which carry the energy and momentum conservation. The vacuum has zero energy and thus the vacuum loops are not calculable. Only within a real interaction can virtual particles "exist". $\endgroup$ – anna v Nov 23 '16 at 9:34
