Being square 🟥 is allright: it will be essentially a condensed version of the following 4 tutorials

Consider this a warning. Factoring small numbers is a bad benchmark. Because the key to factoring small numbers isn’t making the quantum computer "work well". That’s the key to factoring *large* numbers. For small numbers it's sufficient to generate a far-too-large circuit, and light the fuse.

firefox has this, also possibility to select multiple tabs via shift or cmd and then close with cmd+W :)

With people saying their results got debunked even though neither paper actually does or, for that matter, even claims that they debunk their results, I can partly understand not wanting to discuss the paper with said people in the first place.

Beautiful! Did not know that and definitely would have needed that before! F(ρ,σ) = tr(√(ρσ)) is so much nicer! Is there a good reason to still refer to fidelity/matrix inner products using tr[√(√(ρ)σ√(ρ))]?

contrary to its headline, the article makes a pretty good case for dwave imo

Yeah I was actually wondering if "spoofing" is the right english word. I think I meant "debunk", or "disprove" (in an unscientific / loose way)
