What a ride! It's been such a pleasure to be a part of this wonderful project. Thank you @victorvalbert for your vision and for being such an amazing zookeeper!
Big update: the EC Zoo is now a handbook. It spans codes, sphere packings, lattices, designs, groups, and phases of matter. Extensively checked, but not perfect—feedback very welcome:

We all have a favorite characterization of the thermal state: as an equilibrium state, via a maximum entropy principle, from the resource theory of thermodynamics, as a step in learning algorithms, among others.
What is the analogous concept for quantum channels?
Sumeet Khatri and I answer this question in arxiv.org/abs/2508.03993 (short) and arxiv.org/abs/2508.03994 (technical).
I've got a longer post & a thread on other social media platforms for whoever would like a short thread-style summary.
But that’s not true is it. After all, your ears can definitely tell when you play a “wrong” note, even if it’s not written down.
We often argued, “but the best jazz musicians don’t follow the rules, why should we?”
The answer is because we were not the best. We were beginners
How do you track the latest exciting developments in the dynamic and constantly evolving field of quantum information science and technology? You organize a conference with awesome invited speakers and many opportunities for contributed talks. Please join us for #QTech2024! ...
Our amazing confirmed plenary speakers include: Antonio Acin, Markus Aspelmayer, Mete Atature (@MeteAtature), Stacey Jeffery, Richard Kueng (@RichardKueng), Anthony Leverrier (@letonyo), Maria Schuld, Christine Silberhorn, Jelena Vuckovic, ... and more to be confirmed! ...

Conventional thermodynamics dictates which processes are or aren’t allowed. Yet it omits to forbid processes that are too complex to be realistic, such as cooling systems with complicated energy landscapes. Here’s our take on how to fix this omission. arxiv.org/abs/2403.04828 1/
The complexity entropy might be an appropriate measure of randomness in many scenarios. After all, an environment can’t probe a system using complex observables. Applications can lie beyond thermodynamics, including information-theoretic tasks under complexity limitations. 6/
Follow us on our journey to include a notion of time in thermodynamics in our new preprint, which also contains many more details and results. Special thanks to wonderful collaborators Anthony, @nagateja95, @haferjonas, @nicoleyh11 and @jenseisert! arxiv.org/abs/2403.04828 7/7
