At @csic we're partnering with the rest of the QEC4QEA consortium to develop useful quantum applications building on our expertise on quantum numerical analysis and quantum optimization.

One of the things that makes me the most angry about this is that it risks completely erasing the recent innovations that have made distance-learning actually good and useful and capable of massively broadening access to quality education

I can only think, and fume, about what a slap in the face this is to every person who fought and/or died for the right to learn, who were attacked or killed because they demanded to learn. people who would do anything, anything, for the privilege of a homework assignment

The greatest peril from AI is humans abdicating from doing what makes us humans

In case you're interested, CSIC is still looking for experimentalists on quantum technologies. Just keep an eye on these and other calls, or talk to us for possible future openings. elpais.com/ciencia/2026...

“Individual ICE agents get money per head that they detain – the guards told me that,” [...] "administration ordered ICE officials to detain more people, [...]. Reports immediately began to emerge of international travellers being detained by ICE officers." It does not feel very safe.

Quick PSA for all mid-career academics and above: people may be citing articles with your name on them that don't exist.

First day of Quantum Canada Days 2026. Interesting talks and very useful networking meetings to promote CSIC's Quantum Technologies Platform

Good morning Victoria!

Happy to read this blog post vindicating microwave cooking. I use it so often as a low power and quick method to cook healthy recipes. Must find me one of those pyro ceramic pans, though malmesbury.substack.com/p/my-journey...

I vibe-knitted a sweater

Finally found the problem: in accessibility, the option "Mono" was activated 🤷‍♂️ Dunno how that happened. Anyway, removing that and deactivating "absolute" volume in developer options restore the soundstage and eliminate all distortions when playing music in the Pixel 8 and sounds like the laptop.🥳

I got a new pair of sound cancelling headphones. Finally opted for a pair of mid-range Bose QuietComfort SC headphones, which were a bit more comfortable than the Sony ones and sounded very good in the shop. There were some surprises with Android, though... 1/

Forget about using webpages for QR codes. They create indirections, track users and may stop working Step 1: winget install PedroAlbanese.qrencode Step 2: qrencode -o qr.png "https://some.url.to.share" Replace step 1 with your package manager in Linux.

Be careful if you develop a cold and fly long distance. Landing can be quite painful if you don't pay attention to breathing, drinking and swallowing while pressure changes.

Second and last call to submit oral contributions to the Quantum Matter conference, to take place in Barcelona, April 27-30 This is a very exciting and complete conference, covering all aspects of quantum technologies and quantum materials, from research to industry www.quantumconf.eu/2026/

Another one for @quantuminthings.bsky.social "Quantum Business"

Thank god the price of QRAM hasn't increased lately

That is a beautiful color. 2021 aged Liu Bao.

Adding Copilot to the Windows Notepad created a vulnerability that has been recently patched. But it shows that adding AI everywhere is an insane risk. youtube.com/shorts/JUdw6...

The "new" WordPress themes and editors are quite snappy. A simple installation with no plugins has replaced a lot of crappy tools installed by our previous web designer for our quantum technologies network qtep.csic.es 1/

Spanish law has introduced a rather dramatic change that is only recently being enforced: any person that interacts with administration must either have an ID card (NIF) or get an identity number (NIE). This discriminates non-Spanish researchers in many ways 1/

My cartoon for this week’s @newscientist.com

Looking at price increases in my former neighborhood and it's crazy. Close to 100% increase in 5 years for a crappy 45m2 studio.

If the book is as good as this short film, I'm going to have a lot of fun tonight youtu.be/3v8AsTHfAG0?...

It seems in my bank they trust AI a lot. Periodically, we have to provide our ID card as proof of existence and their AI system has decided to change both my name and my father's name based on their scan of the documents, on separate accounts and on separate incidents. Humanity is doomed. 1/

Here's a power metal summary of scipost.org/10.21468/Sci.... It is fairly comprehensive and accurate. The text is generated by codex, the graphic by chatGPT, and the music by ACE-step. The research is of me and my coauthors :) I am honestly impressed by ACE-step.

1/4 RIP Micius 🛰️ The world's first quantum satellite crashed into the Pacific last week (to the west of Ecuador) after an almost 10-year mission Also known as Mozi (& QUESS) it was famously the first to teleport a photon to space (or at least its quantum state) 🧪⚛️ www.nature.com/articles/nat...

We take randomness for granted.
 Early PRNGs were BAD. Thousands of scientific papers used to rely on RANDU, created by IBM in the 1960s.

In 1D space, it looks ok! Map in 3D…you start to see the issues. Now, there *was* a better solution...but it would cost you.

I'm sorry, #Numpy, but this does not make any sense. Indexing by a vector is supposed to make a copy and return a contiguous array. Otherwise your interface is lying: B or R[:,I] is not a C_CONTIGUOUS array.

Nepal golden tips black tea. A bit more astringent, but the Chinese steeping method (direct immersion, more tea, short steeps 5-20s) modulates the release of more astringent compounds, which come out more slowly. Result is very mellow. Best practical thing I learnt in 2025.

There should be a special place in hell for people who steal umbrellas from public spaces in rainy days.

Repetimos migas, pero está vez con el acompañamiento completo (según receta de Encinasola)

Enjoying an aged Liu Bao tea in this quiet Sunday morning. Love these earthy flavors. Take the mind away from the cold. Best thing is that with these loose leaf teas one can then cook (literally boil!) up to a litre of tea for a thermos. Not as nice a gongfu style, but never bitter.

Another very exhaustive video from @techconnectify.bsky.social , only topped in my mind by the dishwasher and rice cooker ones, because these had practical impact in my life.

Implemented category-based caching. The dailyarxiv.com app should no longer bother arXiv so often and be a bit more responsive.

100% agree. Especially since we have author IDs that are matched to the papers when they are claimed!
