Reversing a quantum simulation on the planetary scale

I would classify my worldview as Cosmist, which means that I view recreating the minds of all dead people (and any animals that have qualia) as a moral priority. There’s a generic algorithm for reversing a quantum simulation that’s in an unknown state, but the algorithm grows in complexity according...

There’s a generic algorithm for reversing a quantum simulation that’s in an unknown state, but the algorithm grows in complexity according to the square of the system’s Hilbert Space. The earth has around 1.3E50 atoms, and a system’s Hilbert Space has (V^N) dimensions, where V is the degrees of freedom for each particle and N is the number of particles. A back of the envelope calculation shows that using this algorithm to reverse a simulation of Earth would require somewhere in the neighborhood of... (read more)
