Living in the Future benefit: the combination of Google Maps public transit directions and phone-tap onboard payment makes it SO EASY to take public trams/buses/metros when traveling now. It’s fantastic not to have to resort to taxis just for lack of easy access to the local transit ticketing system

I wish we could develop common standards for

- pulse data
- circuit manipulation (incl. transpilation, routing, optimization)
- calibration & calibration QUALITY data
- measurement results, incl. raw and complex

I got tired of mashing together tools to write long threads with 𝐫𝐢𝐜𝐡 𝑓𝑜𝑟𝑚𝑎𝑡𝑡𝑖𝑛𝑔 and ℳα†ℏ—so I wrote La𝑇𝑤𝑒𝑒𝑡!
It converts Markdown and LaTeX to Unicode that can be used in “tweets”, and automatically splits long threads. Try it out!

The Destruction of NASA Would Be a Blow to Our Collective Imagination
As NASA grapples with major proposed budget cuts and losing some of its most brilliant minds, America’s willingness to look outward is also at risk.

I put out a preprint on machine learning for QEC decoders with some theory about importance sampling for decoding. Takeaway: You can robustly improve ML decoder performance by training on data generated with higher device error rates, sometimes 10x higher! arxiv.org/abs/2505.22741

Aspiring crime writers now have the chance to be taught by “Agatha Christie”, thanks to a course of online video lessons by BBC Maestro.
The videos “starring” the author, who died in 1976, have been made using AI-enhanced technology, licensed images and carefully restored audio recordings. Continue reading...
