I realise parents can be embarrased, in previouas generations superposition was done in private and entanglement was practically a taboo, the end result is people too embarrassed to talk about real problems, 58.567% of all left handed american men can’t sustain an entanglement long enough to satisfy their spouses. I like the idea of a connection between quantum mechanics and consciousness. But if that connection exists it is not easy or obvious and nobody has suggested an experiment that shows its usefulness. Students might like to create their characters in the paint program (such as Paint or Tux Paint). Students should draw their characters in a number of poses. This allows for more realistic movements, such as walking. Students can import digital photographs (Scratch and PowerPoint® both allow users to import images from elsewhere.) MAIN ACTIVITIES From this perspective, the Martinis/Google group’s recent preprint “Characterizing quantum supremacy in near-term devices” (2016) might alternatively been titled “Characterizing the spukhafte Fernwirkungen associated to large-dimension metric isomorphisms in quantum dynamics”. Further discussion of this thought-provoking preprint would be welcome by many Shtetl Optimized readers (including me). Let me try to give some reasons (there are many more) why they are useful: (1) absence of global phase, (2) description of subsystems, (3) definition of entropy.

So the phrase “Damned with faint praise” ( https://en.wikipedia.org/wiki/Damning_with_faint_praise) came to mind when I read Dr Motl’s post. you would also need faster-than-light communication to coordinate the measurement outcomes between different parts of the universe.” Yes, given an initial state, Hamiltonian, and measurement basis, the probabilistic predictions of quantum mechanics can be calculated to arbitrary accuracy by a short computer program running in a large amount of time—so in that sense, QM has very low Kolmogorov complexity (though probably not resource-bounded Kolmogorov complexity, if we define the latter using classical computation). I believe that on the other side of the galaxy there is an alien nerd calculating the billionth digit of Pi. And making allowances for trivial things like number base or method of representation it will be the same digit as we calculate here. I don’t expect that his book will ever be translated into English, but I hope that at least his concept of dynamic information and his conjecture that this dynamic information is conserved just like energy will find its way into discussions about quantum information theory. Maybe those discussions will show that his concept and conjecture is trivial or wrong, but I think that those discussions would be beneficial for highlighting to role of time dynamics in quantum mechanics. Not sure whether those are important for quantum information theory or not. (I hope I didn’t ran into that “damned by faint praise” issue again. In the part of Germany where I come from, praise is used “sparingly”.)

Curriculum

People who don’t know a lot but realize that QC is interesting but don’t oversell it. If they know enough they may thing that its likely SAT is not in BQP, though they may not know the terms. jonas #21 — If the comic links to a particular blog post, then it is in fact linking to the blog. Anyone who finds the post finds the entire blog. The reverse isn’t true; six months from now someone reading the comic will know that Scott Aaronson was involved, but they won’t know that there was a particular blog post associated with the comic, and even if they guess that there might have been, they will have a difficult time finding it. And since Zach’s comics aren’t dated, finding this post will become harder and harder as time passes, since they’ll need to search more and more of the blog. Class of 2020 had finished.I learned a lot by teaching the class on Sunday since March and digesting complex ideas into drawings. Hope you enjoyed it as much as I did. All the recordings can be found here.

Looking toward the quantum future, the preceding considerations provide reason to foresee that practical large-scale demonstrations (or not) of quantum supremacy— whether achieved by photonic BOSONSAMPLING, DWAVE-style SQUID arrays, ion traps, or any other foreseen scalable quantum technology— will rely crucially upon MEEP-like computational tools and philosophical/social insights like Voevodsky’s. gasarch #41: I can say from experience that Oded Goldreich does indeed know a lot, but the lot that he knows is not about QC (and he readily admits as much). I’ve read your thoughts on the many worlds interpretation and dynamical collapse theories but I was wondering what you think of quantum Darwinism?Now let the automata evolve for a billion generations according to its rules without collapsing the superposition. Now you have a superposition of all possible universes that are a billion generations old. But what you also have is a vast network of entanglements. The states of the cells are still in superposition but those states are no longer independent of each other. haha – but how do you propose that happens? Do you say, like Dirac at the 1927 conference, that Nature does all the random jumps? For people who, willfully or not, misunderstand my work and are open to reforming their ways I have a list of references of increasing mathematical precision that I send to help set them straight. This has now become first on that list.

Niraj #27: Not sure if I understand the error. Had the OR/XOR distinction been relevant given the context, the mom could’ve added, “superposition doesn’t mean AND, and it doesn’t mean OR, and it doesn’t mean XOR either.” 🙂For QM to turn probabilistic the way it is described in its axiomatic description, it is sufficient if only the measurement rule is made probabilistic. The system evolution, represented here via the updates, could very well be deterministic. In QM, the Schrodinger evolution is deterministic anyway.
