You're not a true fan of the anime (my tweets) unless you have read the manga (my 110 page arXiv papers).

Thanks to the organizers of #Tqc2023 -- and especially to Lídia del Rio (@MarjBaldwin ) -- for putting together a great conference!

Can we approximate noisy quantum channels with a time-dependent Markovian dynamics from just a few measurements? We answer 'yes', with an algorithm to explicitly retrieve a sequence of Lindblad operators yielding the best-fit evolution to the data. scirate.com/arxiv/2303.089…

I'm confused... isn't this just the textbook scientific process ?

There are too many user interfaces and I think it is a source of general frustration unhappiness and inefficiency. A push for international standardisation of common ones ( like personal information forms) would make the world a much more pleasant place imo.

What strikes me most about the current political situation in the UK is that the current prime minister was effectively elected by the financial markets.

Think about the feeling you get when you hear that Vincent Van Gogh's Sunflowers might have been irrevocably destroyed. Hold on to it. This is the feeling these protestors want you to associate with the climate crisis. Think about where you are directing these feelings.
