Today I spoke about quantum nonlocality in networks at the "Nonlocality: Driver for Quantum Advantage?" workshop at the @lorentzcenter.bsky.social. After the first day of the workshop, I'm eager to see what the rest of the week brings.

Some quantum info researchers are reluctant to learn about non-CPTP maps, but are ultimately left with no Chois.

The IOP Publishing International Quantum Early Career Award - Quantum Science and Technology - IOPscience

I was not expecting this for Christmas, at all. I am truly grateful for having my research being recognized this way. Thanks to @ioppublishing.bsky.social @iopp-quantum.bsky.social for this prize!

2025 is almost over! Looking forward to 2026, when I'll finally do all the things I didn't get to in 2024

Spring School on Near-Term Quantum Computing

The @ccbpp.bsky.social Spring School on near-term quantum computing is back! If you are a young (PhD/MSc) researcher in quantum science and want to get exposed to the recent developments on quantum computing, do not hesitate coming to Benasque on March 15 - 21 next year!

As part of a broader effort to demonstrate AI’s po-
tential in scientific research [1], OpenAI executives have
pointed to a recently published paper by Hsu [2] as evi-
dence that AI can contribute original ideas to physics [3,
4]. Hsu credits GPT-5 with proposing the core idea of the
paper de novo, possibly the first published physics article
where the main idea came from an LLM, and discusses
the methodology in a companion piece [5]. We examine
whether GPT-5’s criterion is correct.

OpenAI leadership are promoting a paper in Physics Letters B where GPT-5 proposed the main idea — possibly the first peer-reviewed paper where an LLM generated the core contribution. One small problem: GPT-5's idea tests the wrong thing. My technical comment: scirate.com/arxiv/2512.0... 1/

A great read by Retraction Watch.

✅ Nice to see that some Article 1 authors, McCoy et al., actively tried to get help from Springer Nature to fix the incorrect citations to their paper.

😐 Seems like Scopus and Web of Science also have the distorted citations.

5️⃣/🔟 In Scientific Reports, 5 of the top 10 most cited articles have an article number of 1.

5️⃣/🔟 In Nature Communications the same: 5 of the top 10 are article 1s.

Coincidence? 👇
