Save the date: sun, sea & science, where wave–particle duality means talks in the morning, surf in the afternoon. Quantum at the Dunes (IIP, Natal 🇧🇷) — School 23–27 Feb 2026 → Workshop 2–6 Mar 2026. www.even3.com.br/quantum-at-t...

Our tutorial "A friendly guide to exorcising Maxwell's demon" (journals.aps.org/prxquantum/p...) is out!

The big question after the tutorial is whether I’m finally done drawing demons?

When I grow up I wanna be like Kristian: talk about quantum gravity while wearing a black-flag t-shirt.

My happiest memories are tied to this university, this office, and that chapter of my life. Even cooler to see my old office mate getting his PhD tomorrow! Finally get to use this picture (taken in 2021, just sitting in my gallery waiting for this moment):

Back in Krakow after 1.5 years. First stop: my old office (just had to see it). Somehow got in and boom 💥: everything was exactly the same: Kamil’s notes on my desk, unfinished (now finished) calcs from Marti’s project, old running gear, and the cactus I bought when I started my PhD!

Sorry for not being clearer - I’m in a shelter at the top of a mountain in Japan right now. Hard to type and be coherent haha

This was formally proven a few years ago! The set of states achievable under thermodynamic transformation follows a partial-order relation called “thermomajorisation”. This is a beautiful result that illustrates your point.

Started reading “the physics of filter coffee” by @jgagneastrocoffee.bsky.social —highly recommend! While browsing around, I found out he also developed an app to measure grind size distribution. Super useful—I’ve always found it hard to get clear grind size advice or compare grinders properly.

Maxwell’s demon was on holiday, just catching up on recent updates… until it thought, ‘Hmmm, I should write a tutorial!'

Very happy to share "a friendly guide to exorcising Maxwell's demon" (arxiv.org/pdf/2503.07740).

Had to say goodbye to my usual Maxwell’s demon for a talk that I’m preparing (not about quantum thermo this time)… but fear not! A unitary transformation later, and voilà—a Gaussian ghost appears to say thanks instead!

Hi all,

I was uncertain about joining a new social media, but after seeing so many great “tweets” from quantum people, I decided to give it a shot!

Below is a gif I made a few months ago while bored—just something to catch your attention.
