If you’ve ever moved into a new home, then you know how difficult it can be to steer bulky furniture through narrow hallways or around awkward corners. A new proof reveals the biggest shape that can slide down an L-shaped hallway. Richard Green reports: quantamagazine.org/the-largest-so…

First talk at #AQIS2023 by Minki Hhan. For classical generic-group model (GGL) algorithms, there is already a classical bound Θ(√|G|). So they classically simulate quantum GGM and apply the bound. (This is not their only result.) Also Betteridge's law of headlines.
Any recommendations for video lectures of interesting courses in quantum computing/information/algorithms/complexity? I've thoroughly enjoyed pretty much anything by @henryquantum, @BooleanAnalysis, and @sevag_gharibian. Would love to hear any suggestions! #QuantumTwitter
The long-awaited enumerative proof of the four color theorem, by David Jackson and Bruce Richmond, is here! Jackson announced this proof in May and it made big news, but then there were apparently some issues that needed to be fixed. Now on arXiv! arxiv.org/abs/2212.09835

I have been teaching geometry and made a million figures in TikZ. My lecture slides are basically a "proofs without words"-style intro to Euclidean, spherical, hyperbolic, affine, and projective geometries: intellectualmathematics.com/geometry/
Really excited about this new paper with Alex Lombardi and Nick Spooner (@_nickspoon). Our motivation: can we prove that important zero-knowledge (ZK) protocols (such as [GMW86] Graph Non-Isomorphism (GNI) or the [FS90] protocol for NP) are ZK against quantum verifiers? 1/14

🧵Here's a trick. You have an algo to compute stuff about its input x. It also takes in α, δ in (0,1], runs in time O(log(1/δ)/α), and succeeds w/ proba 1-δ as long as x satisfies α(x) > α. If not, it outputs ⊥. Of course α could be a very loose bound on α(x)! 1/
