"I enjoyed publishing some cheeky ZKPs, but I don’t think it’s the right strategy moving forward. The benefits are negligible, and the costs are many. We should just publish openly." 🚀

Blog post: "The French have the Quantum Circuits" algassert.com/post/2602 André Schrottenloher just published a preprint showing how to construct quantum ECDLP circuits with costs similar to the ones in our zero knowledge proofs.

Everything makes so much more sense once you realize whether you are a lumper or a splitter en.wikipedia.org/wiki/Lumpers...

First time I'm seeing arxiv.wiki (it's now (?) automatically linked on scirate. Looks like a great initiative, right up my alley!

Genuine question as I am not up to date: were there major innovations in neutral atom computing that circumvent the problem of having to physically shuttle atoms, leading to unfortunate (logical) clock rates?

you know how they say, sometimes 115 quantikz circuit diagrams say more than a thousand words.. new preprint "parameter-optimal unitary synthesis with flag decompositions" w/ @dwierichs.bsky.social Guillermo and Nathan scirate.com/arxiv/2603.2...

typos ftw: I'd much rather read your raw scribblings than your polished and soulless AI-generated deliberations

@mozilla.org Firefox lowkey the best browser for these two features alone: - cmd+tab cycles through tabs in recently used order - you can go back and forth between hyperlinks _within_ a pdf using the back and forward buttons

Another way to view it: Great! Now we have a very good initial state in form of that MPS to run quantum algorithms on 🙃

My recommendation: read the paper, an excellent work marking IMHO another milestone for quantum chemistry, congratulations to all authors. To add to the cited post, the most important conclusions of the work are highlighted in the picture, a breakdown will be provided in the comments.

I will not tire of whining about overleaf and quantikz speeds

All I want for christmas is a (better) quantikz equivalent for @typst.app (and arxiv+journal support) Using overleaf.com after typst.app just feels like going around in a horse-drawn carriage in 2025 - gets you from A to B, and is kinda cool and vintage, but just extremely slow and cumbersome.

I heard someone say reverting daylight saving time in October is like "trading one hour of sleep (once) for five months of darkness" and now I cant unhear it.

The first novel thing I did in quantum computing was find a way add +1 to a register using O(1) space and O(n) gates. For 10 years I've wanted to know how to generalize that from x+=1 to x+=C... and I finally figured out a way to do it! arxiv.org/abs/2507.23079
