What does the quantum butterfly effect tell us?

  1. Aug 23, 2013 #1
    I'm interested in interpretations and comments regarding this Wikipedia snippet:


    http://en.wikipedia.org/wiki/Butterfly_effect#Examples


    This idea is new to me. My limited understanding is that the macroscopic butterfly effect is related to non linear system effects....and slightly different initial conditions....but here it seems the initial condition is fixed, so how does the Hamiltonian change...what does that mean?? Is this 'quantum butterfly' effect saying anything about our linear [superposition] principles in QM?

    thanks.

    What article is that? I can't find that statement in the article I linked.

    It's in one of the references linked to from the wikipedia article.

    Nugatory:
    but which one? I interpret the reference as different from what Wikipedia states.

    DrClaude:
    This, too, I interpret as likely distinct from the case Wikipedia claims.

    It's the ref. [16] in the Wikipedia article, and which appears in the citation in your first post.
