You are made of quantum mechanical interactions too. When you 'measure' you interact with the system you want information out of. I cannot predict my sensory experiences of interacting with a 2^-0.5 * (|0> + |1>) system. But I know it is obeys several mathematical laws below the bonnet. The Born probabilities are an open problem, probably to be solved with Evidential Decision Theory and Physics together. Not by sweeping it under the rug of "Collapse." | |

| May 10, 2013 at 16:45 | comment | added | Alex A | I disagree, for various reasons. First, how can you say that QM is deterministic? Can you predict with certainty the result of, let's say, an energy measurement of a two-level system in the state $\frac{1}{\sqrt{2}} (\left|0\right> + \left|1\right>)$? Also, if you haven't heard of non deterministic theories in physics, I suggest you to check out spontaneous collapse models, where the indeterminism is explicit in a stochastic extra term on Schrödinger equation (I'm referring mainly to the GRW theory). | |
