In our new paper on arXiv today, @CraigGidney and I explain the techniques we used to make PyMatching 100x-1000x faster: arxiv.org/abs/2303.15933 Our sparse blossom algorithm is a variant of the blossom algorithm that directly solves the decoding problem relevant to QEC. 1/

My favorite tidbit from today's NQIAC meeting... Ritter: The space program generated lots of enthusiasm for STEM. It was tangible. It's harder for people to grasp quantum. @preskill: We need a Hilbert space program.

The Game of Life can be emulated, recursively, inside the Game of Life

Tiny changes to the order in which you update positions x and velocities v can be the difference between your simulation blowing up or dying down. But for many systems, *symplectic* integrators guarantee energy is preserved forever. Full lecture here: youtube.com/watch?v=Fi9xu3…

How a book written in 1910 could teach you calculus better than several books of today [Calculus Made Easy, by Silvanus P. Thompson, 1910 - full text pdf: bit.ly/2pThkf1 or with the table of contents: calculusmadeeasy.org]

Newly confirmed: The following repunit number is prime. mersenneforum.org/showpost.php?p…

The Transformer is a magnificient neural network architecture because it is a general-purpose differentiable computer. It is simultaneously: 1) expressive (in the forward pass) 2) optimizable (via backpropagation+gradient descent) 3) efficient (high parallelism compute graph)

Does anyone at @iqoqivienna know what happened to the 'official' list of Open Quantum Problems at oqp.iqoqi.univie.ac.at (archived at web.archive.org/web/2019120600…)? The website has been dead for months. It seems that all previous iterations of the list on other sites are gone too.
