Is the universe a quantum computer?


The universe is quantum mechanical, and its dynamics can be simulated precisely and efficiently using quantum information processing. The amount of quantum computation required to perform this simulation is finite and has been calculated. Consequently, there is no obvious way to distinguish the universe from a very large quantum logic circuit.
