The laws of physics are expressible in terms of computer programs is that they are in fact computer programs perhaps the existence of computers in nature is a special case of the ability of computers to emulate other computers. The entropy of any region of space cannot exceed a fixed constant times the surface area of the region Beckenstein 1981. This strongly suggests that the complete state space of any spatially finite quantum system is finite so that in fact it would contain only a finite number of independent qubits but even if this most optimistic quantum computation-centered view of physics turned out to be true it would not support the most ambitious ideas about information at the foundation of physics.
