 Apr 4 awarded Popular Question Mar 25 awarded Nice Question Mar 14 awarded Yearling Mar 10 revised How is the range of $x\cdot s$ in Simon's algorithm restricted to $\{0,1\}$? Fix summation indices Mar 10 comment How is the range of $x\cdot s$ in Simon's algorithm restricted to $\{0,1\}$? Got it! Shouldn't that be either $x\cdot y \equiv\sum_{i=1}^n x_iy_i\pmod 2$ or $x\cdot y = (\sum_{i=1}^n x_iy_i)\bmod 2$ Mar 10 suggested approved edit on How is the range of $x\cdot s$ in Simon's algorithm restricted to $\{0,1\}$? Mar 10 accepted How is the range of $x\cdot s$ in Simon's algorithm restricted to $\{0,1\}$? Mar 10 comment How can all information be localized if local realism is dead? (Some questions you might be able to help with: (1) recommendations for drawing quantum diagrams — circuits and Bloch Spheres; how the "mod 2" dot product gets introduced into Simon's algorithm: see my last comment on the — confused — answer, which I think is the answer I'm looking for.) Mar 8 asked How is the range of $x\cdot s$ in Simon's algorithm restricted to $\{0,1\}$? Mar 8 comment How can all information be localized if local realism is dead? And, critically, the mixed state version of a BS is really a kind of expected value (the pure state is too, I suppose, but a degenerate one, of a random variable with a single certain outcome). Right? Mar 8 accepted How can all information be localized if local realism is dead? Mar 8 comment How can all information be localized if local realism is dead? Still pondering this excellent answer. There a few things I'm stumbling over, notably that, as beginner, the Bloch Sphere representations in the diagram are showing something different than I'm familiar with. I'm at the point of just thinking of the BS as a way of representing the state of a cubit; but here they're being used to represent a kind of PMF (the marginal PMF of the cubit's state) such states (actually something more like the expected value of that PMF). Is that about right? Mar 7 comment How can all information be localized if local realism is dead? Thanks! Could you say a bit more about "marginal state"? Mar 7 comment How can all information be localized if local realism is dead? Can you make this a bit more beginner-accesable (and draw some pictures; ideally as circuits)?

Sep 30 comment What is the angular distance between Ptolemaic perigees of Mercury? @Cicero: I doubt it. It's really about the details of the calculation. HSM hasn't proven to be very quantitative.
