There are multiple classical computational traces in the quantum computer. 2. If the classical computational traces are computations of conscious minds, there are multiple conscious minds and points of views. 3. The quantum computer maintains the superposition of the multiple computational traces by virtue of being isolated from the environment. 4. Our own minds are isolated from the rest of the environment for some definition of the environment (e.g. a sphere with a 200 light year radius centered on Earth). 5. From the perspective of a scientist outside this sphere, we can be viewed as a superposition of many possible states. 6. Hence we experience "many worlds" in the sense that the wave function for the state of the earth becomes a superposition of huge number of possibilities. (From the POV) of the scientist outside the sphere. Jason -- You received this message because you are subscribed to the Google Groups "Everything List" group.
