why would I ever again share a well formulated open research question in an open problems session of a conference?

I am a researcher in mathematics and physics working on complex quantum systems and quantum field theory. Recently, I am also interested in earth observation.
"We're all worried," as what it means to do research (in my field, Theoretical CS) seems to be shifting, and shifting fast. What to do? Senior researchers must lead by example, knowing that not everything will pan out. What I'm suggesting below may not work everywhere, but here's my own advice: 1/
Some initial thoughts, and a complicated mix of feelings. Wow. I mean, Erdos problems are cool (I genuinely mean that), I didn't know about the Jacobian conjecture before it got disproved. But this newest batch from OpenAI hits home in a way the previous announcements did not.

Quantum Information Processing research in the age of AI
Dear colleagues, Over the past weeks there have been more and more results in which AI models played a crucial role, not only in mathematics and theoretical computer science, but right at the heart o...

The point isn’t to write an essay (or solve the problem sheet, etc). It’s to learn. It’s a foil against which the student can struggle and, in so doing, think. I’ve not seen this video by Burnham, but the wider sentiment — “essays are pointless because AI can write them” — is depressingly common.
Charlotte Weatherill@ckweatherill.bsky.social · last wk.Full of despair today. Massive lay offs in social sciences and humanities across the country, Burnham puts out a video saying 'AI can write an essay', and my university is busy integrating co-pilot into all staff and student computers. We are being told we're defunct and there's no resistance.
The last point is actually very troubling: there is a huge inequality in the access to frontier models right now. Some people are simply not aware of this AI revolution, some cannot afford paying 200$ per month, especially in less developed countries (and even in developed!). 5/n
I tend to agree with Tobias. It will be interesting to see near-term changes in the valuation of certain aspects of research. An important problem I see is who can afford access to frontier models and how the scientific community should address this. tjoresearchnotes.wordpress.com/2026/07/28/p...

While the Fields Medal celebrates the under-40s, the mathematician Joan Birman has, at the age of 99, solved a major open problem in representations of the Braid groups, a topic she has worked on for more than 60 years.
We're pleased to announce the key dates for QIP 2027, as follows (refer to the website qipconference.org/2027/ for up-to-date information). We look forward to your participation!
I think this document does a nice job of articulating and balancing the many concerns people have about AI, the potential benefits, the spirit of mathematical research, and the reality of the current situation. I signed it.

The largest fundamental science agency in Europe will save €1.4 million annually by breaking free from Clavariate Analytics' huge databases of references and citations. "We have worked for free to lock ourselves collectively into a paid system", one head of the CNRS explains - but no more! 🎉

Like embezzlement of entanglement but not von Neumann algebras? Check out arxiv.org/abs/2509.15749 where we show explicitly that generic Gaussian fermionic states provide universal embezzling families. Plus: A novel bound relating trace distance of Gaussian states to their covariance matrices.

Embezzlement of entanglement allows to extract arbitrary entangled states from a suitable embezzling state using only local operations while perturbing the resource state arbitrarily little. A natural...

If you find it strange that the inequality involves two arbitrary states, operator-valued weights come to your aid, giving meaning to the inverse of a state. This way, the inequality becomes a statement about the cp-odering of maps from B(H) to the subalgebras associated with systems B and BC.
