If I gave you these evolution rules, can you tell me what will stay constant during the evolution? Very belated post on recent work on hydrodynamics of circuit systems! Work with Friedrich Hübner, Juan P. Garrahan, and Benjamin Doyon. See more here: arxiv.org/abs/2503.08788 (1/7)

Tutorials begin at QEC2025 at @yaleqi.bsky.social. Here is an artistic rendition of some famous codes at the Google Quantum AI tutorial.

Surprisingly LLMs have only recently surpassed the usefulness threshold for me: Generating an iCal file from a pdf or a website. Few months ago they would fail miserably, but now they can do it, with some back and forth. Now I'm fully convinced that they're going to enslave us all

Le Monde reporting that a French scientist traveling to Houston to attend a conference was denied entry to US after a search of his phone & computer revealed messages critical of Trump's science cuts, "which [says CPB] conveyed hatred of Trump & could be qualified as terrorism".

I believe the technical term is 'rawdogging'.
OK, so naked running.

Apparently this means running without GPS, music and any other tech.

I wish I knew this an hour ago.

Here are some slides on our latest work on inferring the position of a random walker from its noisy images, now out in PRE: go.aps.org/3XbRTUp (1/8)

If I gave you noisy 'images' of a moving object, is there a threshold signal-to-noise ratio where you cannot infer its position? It turns out that the answer is 'no' in 1D, but 'yes' on a tree. This transition is like MIPTs in quantum systems. Work with @austen.uk now out in PRE: go.aps.org/3XbRTUp
Planted directed polymer: Inferring a random walk from noisy images
We introduce and study the planted directed polymer, in which the path of a random walker is inferred from noisy "images" accumulated at each time step. Formulated as a nonlinear problem of Bayesian i...

Whenever I see phase diagrams of spin glasses, I see that the phase boundary of SG from the Nishimori point to zero temperature is a straight line. Is there an easy way to see why this is so? #physics #spinglass #qec

TLDR for me/others: Diffusion model to predict image at new time and camera loc given image at diff time and diff camera loc.

Trained on synthetic data with all of required data, augmented with real vids with diff time but static camera and static time but diff camera angles. Impressive!
Stop watching videos, start interacting with worlds.

Stoked to share CAT4D, our new method for turning videos into dynamic 3D scenes that you can move through in real-time!

Is it possible to get less photos of space here? Half my feed is just space photos.
