Does there exist a large scale scalable tool (engine) for simulating the universe that incorporates both quantum mechanics and cosmology, i.e. micro & macro scales?
(It would be best if this tool simulated the entire universe using quantum mechanics only, without any corrections to the model that come from the macro scale)
Additional resources (from @Qmechanic):
Nobody has managed to simulate anything except the most trivial quantum systems on a classical computer. One of the reasons people are so keen to develop quantum computers is that they are ideally suited to simulating quantum systems and real life problems that involve QM, most notably things in chemistry and biology. Quantum computing promises to be exponentially faster than classical computer for these tasks. Another approach is to use existing QM systems to simulate other QM systems ie a something like a quantum analog computer
