no nuke this isn't a cure for humanity it is the destruction of the universe, our planet wouldn't have anything left the entier galixy would be rendered to pure energy, everything unzipped, a quantum vacume colapse would be like pulling on the loose string of the universe, everything every were would be destroied, and I do mean EVERYTHING EVERYWERE, black holes 50 billion lightyears away would be destroied, it would spread through the fabrick of space not simply destroying all matter but undoing the very timespace it'self.
with a quantum vacume colapse what happens is a new simpler more stable form of space is created, sence it is simpler and lower energy when you have our current space exposed to it it colapses into the new paradigm and the effect spreads through all space wihout any care given to what if any matter is in the reagon. if made into a waepon it would make that wormhole weapon form farscape seem like a fire cracker. its a weapon that kiils reality, not the people within it, and it canot be contained.
