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.

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...

Proof inflation

I have been thinking a lot about how social dynamics are going to shift in the new era of cognitive abundance. I don’t pretend to have any kind of crystal ball, but there are numerous histori…

It's not necessarily the end of mathematics, but it's hard to see how the all the social structures that support the subject will be able to avoid major disruption over the next few years.

Whistleblowing is vital, but rarely risk-free ⚠️ Could the #quantuminternet change that? Join this webinar with Frederik Hahn from Technische Universität Berlin tto explore quantum-enabled anonymity, network architectures & real-world potential. 🔗 quantuminternetalliance.org/event/quantu...

Last year, I became interested in the question what happens if we impose computational efficiency onto information theory. In our latest paper, we analyze how this changes the amount of information that can be transmitted over a channel -- spoiler alert: a lot! scirate.com/arxiv/2601.1...

The computational two-way quantum capacity

Quantum channel capacities are fundamental to quantum information theory. Their definition, however, does not limit the computational resources of sender and receiver. In this work, we initiate the st...

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! 🎉

CNRS@cnrs.fr · 8mo ago

From January 1st 2026, the CNRS will cut access to one of the largest commercial bibliometric databases, Clarivate Analytics' Web of Science, along with the Core Collection and Journal Citation Reports.

🥳I am very happy to have been awarded an ERC Starting Grant that I will use to start my own group and explore the large-scale entanglement properties of complex quantum systems. This would not have been possible without my fantastic collaborators and supervisors. A big "thank you" to all of you! 🙏
