Rafael Wagner @quantumrw.bsky.social · 03/08/2026APS will charge 1,750$ for authors to publish in APS Open Science (a recently introduced journal expected to have a lower impact than PRA) It's hard to imagine who would be willing to pay so much to publish in such a lower-impact journal, especially as free alternatives exist shorturl.at/LRyF2 110
Rafael Wagner @quantumrw.bsky.social · 01/08/2026Boxed equations, of course arxiv.org/pdf/2607.25838 120
Rafael Wagner @quantumrw.bsky.social · 01/08/2026AI-generated paper starter pack: include your prefered! Starting with a classic. AI-hallucinated references! arxiv.org/pdf/2607.07808 291
Rafael Wagner @quantumrw.bsky.social · 16/07/2026Had a great (family-friendly!) networking experience. I had the opportunity to meet many (old and new) Humboltian friends. Can't wait for next year! 120
Rafael Wagner @quantumrw.bsky.social · 16/07/2026Back from the Alexander von Humboldt Foundation Annual Meeting in Berlin—where networking was as heated as the weather (>40°C, pun intended)! ☀️🔥 The three of us - Me, Yenni P. Acero Ortiz and Gabriela Wojtowicz - represented the ITP-Ulm's long-standing tradition of Humboldians. #Quantum #AvH #Ulm 150
Rafael Wagner @quantumrw.bsky.social · 19/03/2026[Portuguese post!] Vitória importante para os acadêmicos! Bolsistas agora vao ter acesso à seguridade social. É uma vitória da ciência!!! 000
Rafael Wagner @quantumrw.bsky.social · 10/11/2025Had a great time in Paris! Talked about our recent preprint arxiv.org/abs/2509.10949 #QuiDiQua3 was great, lots of greats discussions, and talks. Happy also to catch up on some good friends :) Can't wait for #QuiDiQua4 (next year in Brussels!) #QuantumInfo #Contextuality #QuantumOptics 170
Rafael Wagner @quantumrw.bsky.social · 05/11/2025And my Institute at the university of #ulm is well represented by a talk from Tobias on quasiprobability distributions and uncertainty relations. #Quantum #UniUlm 040
Rafael Wagner @quantumrw.bsky.social · 13/10/2025Rudi B. P. Pietsch, one of the PhD Students I co-supervise (with prof. Plenio) here at the University of Ulm #UniUlm recently published his first ever research article at #PRA! Huge congrats to Rudi and Dani! Its the first of many : ) #QuantumThermodynamics journals.aps.org/pra/abstract... 010
Rafael Wagner @quantumrw.bsky.social · 23/09/2025As one of our main results, we employ novel inequalities to show that for a broad class of energy-conserving interactions there is a critical time tau such that for any time t such that 0 < t < tau an observed heat anomaly implies a violation of a noncontextuality inequality — i.e. contextuality. 100
Rafael Wagner @quantumrw.bsky.social · 22/08/2025I've only recently discovered this nice conference :) If you like work with contextuality, nonclassicality of quasiprobability distributions, weak values, entanglement, and phase-space quantum related topics? Check out QuiDiQua3! This year in Paris! quidiqua3.sciencesconf.org?lang=en 030
Rafael Wagner @quantumrw.bsky.social · 08/08/2025Maybe the most direct abstract ever? Recently a paper in nature made the bold claim that their results constitute real challenges to Bohmian mechanics www.nature.com/articles/s41... In this preprint arxiv.org/abs/2508.04756 Bohmians fight back!! The results challenge Bohm? "No, it does not." 110
Rafael Wagner @quantumrw.bsky.social · 14/07/2025Awesome talk by Christopher Fuchs on the history of quantum mechanics here at the University of Ulm #UUlm #QuantumInformation #QuantumFoundations 050
Rafael Wagner @quantumrw.bsky.social · 05/06/2025Filipa Peres talking about magic (aka nonstabilizerness) monotones, quantifying magic, set magic, and the task of witnessing magic! 🪄🪄🪄 #FoQaCiA workshop #QuantumComputation #Quantumresources 021
Rafael Wagner @quantumrw.bsky.social · 05/06/2025Miriam Backens talking about Pauli flow and an algebraic formulation of it leading to faster flow finding algorithms! #FoQaCiA workshop #QuantumInfo 000
Rafael Wagner @quantumrw.bsky.social · 04/06/2025Lorenzo Catani talking about novel extended Wigners friends arguments using prepare-and-measure scenarios. #FoQaCiA #Quantum #INL 030

Rafael Wagner @quantumrw.bsky.social · 03/06/2025Adan Cabello now telling us how he wants to go beyond Bell and use Bell inequalities... ...to bound the ability of superdeterministic models of violating Bell inequalities! 031
Rafael Wagner @quantumrw.bsky.social · 03/06/2025#FoQaCiA school ended and the workshop is just starting. First talk on higher order quantum information by Marco Tulio Quintino. 021
Rafael Wagner @quantumrw.bsky.social · 19/02/2025Final update. I got the visa! 🎉 Lets go! Can't wait to start working in Germany! #Science #Quantum And I got here in a beautiful day! 2110
Rafael Wagner @quantumrw.bsky.social · 16/02/2025Me, Lorenzo Catani and Som Kanjilal working on our draft right now 081
Rafael Wagner @quantumrw.bsky.social · 28/01/2025Many discussions continued in the streets of #USTC, luckily China is so advanced in quantum technologies that Bloch spheres are everywhere, making it easier to explain concepts such as quantum coherence. 061
Rafael Wagner @quantumrw.bsky.social · 28/01/2025Last December I had the opportunity to talk about our recent results on quasiprobability distributions IN CHINA (still can't believe it). Had a great time at #USTC Hefei, talking with the group led by Prof. G C Guo and co-supervised by Yu Guo, together with Prof. Shuming Cheng. Great discussions! 120
Rafael Wagner @quantumrw.bsky.social · 03/12/2024Can you find this little guy that paid a visit? :) 020
Rafael Wagner @quantumrw.bsky.social · 27/11/2024arxiv.org/abs/2411.15964 This week #QuantumFoundations arXiv. They introduce a theory, different than QT only by the tensor product rule. They reproduce, e.g., all Bell correlations. I wonder what it may imply to Q Mereology or gaps between real and complex QT in Networks. It was a nice read 🙂 0122
Rafael Wagner @quantumrw.bsky.social · 22/11/2024Check mate in 6 and it starts with an amazing move!!! 100
Rafael Wagner @quantumrw.bsky.social · 20/11/2024I am a PhD Student and I am also part of a project called #FoQaCiA, which for Italians is a super funny name for a project. The outputs of this project are being displayed at the Quantum Flagship booth of the European Quantum Technologies Conference #EQTC2024 in Lisbon, this week. 140
Rafael Wagner @quantumrw.bsky.social · 18/11/2024New work from my colleagues Raman Choudhary and Rui Soares Barbosa from the #QLOC #INL arxiv.org/abs/2411.09773 If you are interested in how quantum information and #foundations relate to one of the deepest problems in graph theory described by #Ramsey's_theory, check out their recent preprint!! 130
Rafael Wagner @quantumrw.bsky.social · 08/11/2024Happy to share that there is a new paper out! :) With Carlos Fernandes, Leonardo Novo, and one of my PhD supervisors Ernesto Galvão, we have investigated an intriguing new quantum resource called 'quantum imaginarity' from a basis-independent perspective! journals.aps.org/prl/abstract... 131
Rafael Wagner @quantumrw.bsky.social · 06/11/2024Happy to share a new work recently published in the Physical Review A. We show that there is a meaningful and good way of extending the existing treatment of KD representations to states (called KD quasiprobability distributions) for every quantum process!! journals.aps.org/pra/abstract... 020
Rafael Wagner @quantumrw.bsky.social · 30/10/2024Happy to have presented at DICE 2024 about my recent work! arxiv.org/abs/2406.09715 On the connections between contextuality and anomalous heat flow! It was also my first conference talk in person of my PhD :) (I had given an online talk for a conference held by the Perimeter Institute) 011
Rafael Wagner @quantumrw.bsky.social · 09/10/2024Professor Streltsov presenting connections between catalytic and asymptotic transformations in the #resource_theory of quantum entanglement #QID2024 Last day of a great conference here in Warsaw! 000
Rafael Wagner @quantumrw.bsky.social · 08/10/2024Ana Belèn Sainz, researcher from #ICTQT and #FoQaCiA partner talks about Activating post-quantum steering to US a #QID2024!! #Quantum #Postquantum 030
Rafael Wagner @quantumrw.bsky.social · 01/10/2024Most important figure of my PhD: It gives a complete characterization of the set of all possible third-order Bargmann invariants Tr(abs) where a, b, c are quantum states. 010
Rafael Wagner @quantumrw.bsky.social · 26/09/2024Bluesky now has over 10 million users, and I was #4,839,982! Perhaps I was kind of a late user compared to many I see posting this here. I wonder if we can find the user 9,999,999 or users with other funny numbers. 010
Rafael Wagner @quantumrw.bsky.social · 18/09/2024#DICE2024 Wednesday! Learning so much about #quantum_gravity 020
