Frits Verhagen successfully defended his thesis "Classical And Quantum Information Measures Characterizing Convertibility: An Axiomatic Approach". 🥂 Congrats!👏 He was advised by @marcotomamichel.bsky.social and Erkka Haapasalo. Frits will be starting a postdoc at NTU. All the best, Dr Frits! 🎓️

New preprint out with @marcotomamichel.bsky.social ! Projections with Respect to Bures Distance and Fidelity: Closed-Forms and Applications scirate.com/arxiv/2602.1... We derive simple closed-form solutions for fidelity / Bures/purified distance projections to various sets of interest.

A meme indicating how various objects in quantum information (pretty good measurement, Petz recovery map, Leifer-Spekkens state over time, and others) are shown to be fidelity/Bures projections in our article.

The last defence this year 🥳💐 Congratulations to Hu Yanglin for successfully defending his thesis, "Quantum Oblivious Transfer: Bounds and Applications", on how to protect privacy with quantum technologies and how to learn quantum systems efficiently. He was advised by @marcotomamichel.bsky.social
