We are having a very nice workshop on macroscopic superpositions in levitated systems. My latest preprint is arxiv.org/abs/2509.17081. Can you guess in which direction my interests are evolving? :)

A pity that I don't work in topological quantum computing: I could have used this Andalusian motive in my talks.

Have you got a PhD offer from a country that may revoke your visa? Let's have a chat 😉

Reinhard Werner giving a talk about von Neumann and quantum, competent and clear as usual.
On this slide, the deep origin of why quantum information people don't like most quantum textbooks. It's about the representation of measurements: vN's axioms ended up missing POVMs.

Fluctuation relations in the statistics of UNO:

If this makes you laugh (at us) and then makes you think (about fluctuation theorems), consider nominating us for the igNobel prize :)

The Symbolic Weight of Yale-NUS's Discarded Books Uni students care a lot about books—who knew?

www.ricemedia.co/the-symbolic...
"The root of the matter—according to NUS, at least—was that the school didn’t realise that their students were interested in the books. Which, when you think about it, is quite absurd for an actual university to state."

Workshop Singapore - Munich: a statement of priorities.

Observational entropy with general quantum priors Observational entropy captures both the intrinsic uncertainty of a thermodynamic state and the lack of knowledge due to coarse-graining. We demonstrate two interpretations of observational entropy, on...

BS relative entropy is actually useful :)

One of those spam conferences -- and not even on spectroscopy.

18 years ago like today I left Geneva to take up the job that is still mine. Celebrating with my group, and thinking of all the amazing people I got to meet.

It should be thinking about new research directions like me...

One of those times when I have to do this with my research. Let's enjoy the ride!

I should join Signal, I heard you may be added to interesting group chats 🤔

The talk of my postdoc was more impactful than mine. That's how it should be: place aux jeunes!

Quantum resource theories looking like an exercise in esoteric theology of an Italian heretic (the speaker was Japanese, which makes this either entirely coincidental or even creepier).

The state of a quantum system is not a complete description for retrodiction A mixed quantum state can be taken as capturing an unspecified form of ignorance; or as describing the lack of knowledge about the true pure state of the system ("proper mixture"); or as arising from ...

The past state of a quantum object depends on your beliefs: arxiv.org/abs/2502.10030
