New preprint: Not too long ago, Marco Tomamichel and I gave a new definition of quantum f-divergences (see below). Now, we teamed up with Salman Beigi to dive deeper into their properties and how they relate to previous definitions: scirate.com/arxiv/2501.037…

I have an opening for 3 ERC-funded postdoc positions in my group at SNS in Pisa. If you are fascinated by quantum resources, entanglement, and quantum Shannon theory, don’t hesitate to apply! Starting date ~Sept 2025, salary ~2,800 euros/month. Details below:

Uhlmann's theorem states that the fidelity of two states rho and sigma can be expressed in terms of their purifications (where the fidelity simplifies). In arxiv.org/abs/2502.01749 we (with Giulia Mazzola and Renato Renner) generalize Uhlmann's theorem to Rényi relative entropies.

CQT’s Marco Tomamichel and his collaborators settle a long-standing conjecture about how much entanglement can help in communication. ✉️ Our story: bit.ly/4aX6M2z The work in Physical Review Letters: bit.ly/4hv8cnl

If you find yourself writing a bullet point list and passing it to GPT to make a "proper" article, it's often better to just give people the bullet points. The GPT adds "wordcel noise" that the reader has to struggle to extract useful info from more than it adds useful context.

Mario Berta talks about our joint results in arxiv.org/abs/2408.15226 -- also with Marco Tomamichel -- at #QIP2025

That's it from me here - I am going dark. I have given up hope that this place can be salvaged from the misinformation hellscape it currently is and thus won't be contributing content. You can find me elsewhere!

And finally, to round out our coverage of Day 4, the most popular evening activity for QIPers: DRINKING! Watts & Ward

Final-year CQT PhD student Enrique Cervero recently capped an internship at JPMorgan Chase by co-authoring a paper in Nature. 💬 We catch up with him about his experience, and what he is working on next: buff.ly/wOUWY51 📄 The paper: buff.ly/F5SuHM9

Outside of work, CQT PhD student Enrique Cervero kayaks. 🚣 "Some of the best views of Singapore are in the middle of Kallang reservoir," he says. buff.ly/wOUWY51

I am hiring a postdoc in quantum metrology / quantum error correction at the University of Sheffield, UK, with expected interviews around June 2025. The position is fixed-term for 27 months. Deadline May 23, 2025. Apply at link: jobsite.sheffield.ac.uk/job/Research-A…

We are currently looking for a postdoc. If you are intrigued by Singapore and CQT (and you should be) and have experience in mathematical aspects of quantum information, especially with information measures, quantum cryptography or learning theory, get in touch!

Heartiest congrats to our NUS faculty members who have been promoted to full professors! We salute you for your achievements and thank you for your contributions to our University. Check out NUS President’s congratulatory post at instagram.com/p/DJ3tMcJyxPo! #NUSExcellence #NUSImpact

👏💐 Congrats to PhD student Roberto Rubboli who successfully defended his thesis, "Optimization and Additivity of Quantum Relative Entropies"! He was advised by @MarcoTomamichel. Next, he will join the group of Daniel Stilck França at the University of Copenhagen. All the best!

🍾💐 Celebrating a successful thesis defence by Josep Lumbreras Zarapico!! 🍉🧀🍪 Advised by CQT's Marco Tomamichel, Josep defended his thesis "Bandits Roaming Hilbert Space". He will next join Mile Gu’s group as a research fellow. Congratulations and all the best, Dr Josep!

Congratulations to CQT Principal Investigator Marco Tomamichel who has been awarded the prestigious National Research Foundation (NRF) Investigatorship. He receives support for a five-year programme of research starting in August 2025. buff.ly/QrAJWkn
