The Future of Computer Science
... A complexity-theoretic argument against hidden variables? A. 2004: Suppose that in addition to the quantum state, there were also “hidden variables” recording the “true” locations of particles (as in Bohmian mechanics). Then if you could sample the hidden variables’ entire histories, you could solv ...
