I'm considering how the 2nd law of thermodynamics (2LT) might necessitate quantum mechanics.(adsbygoogle = window.adsbygoogle || []).push({});

For it would seem that QM effects always consist of a superposition of states. Each state has a particular structure, and there is a number of these states that must be in quantum mechanical superposition.

Now if each alternative state has a structure, then there must be some information (negative entropy) associated with that structure. But then the number of alternative states increase which seems like an expansive increase in entropy, right? So I wonder if the 2LT requires alternative state to increase entropy in order to compensate for the decrease in entropy (the increase of information) associated with each structure of each alternative. Or perhaps the increased number of alternatives is compensating for the expectation state.

So along these lines I consider the types of structure possible. I remember that the more symmetrical a structure the less information associated with it because it is the least complex structure. So this raises the question for me as to the meaning of "symmetry breaking" processes. Is QM "the" symmetry breaking process? If added complexity developes, this represents more information than the perfectly symmetrical states. So must this be accompanied by a number of quantum mechanical alternatives to be in superposition in order to at least balance entropy? Thanks.
