It outlived the best qubit stored in the same levels, though another group questions that comparison.Sun, 25 Oct 2026 00:00:00 GMTquantum-error-correctiontrapped-ionsquantum-memorypeer-reviewedhttps://tkdb.pages.dev/blogs/science-mathematics/graham-rearrangement-conjecture/https://tkdb.pages.dev/blogs/science-mathematics/graham-rearrangement-conjecture/Four papers from partly independent groups together show that any set of nonzero numbers on a prime-sized clock can be ordered so no partial sum repeats, as long as the prime is large. The final piece is still a preprint.Sun, 25 Oct 2026 00:00:00 GMTcombinatoricsadditive-combinatoricsprobabilistic-methodgraham-conjecturepreprint
