Four QUICK sloths (🦥) from @jku.at in Hogwarts, aehm Oxford: Mario, Marwa, @dgarciamartin.bsky.social and yours truly. QCTiP 2026 (qctipconf.github.io) has been a blast. This was my first time as a PC chair and I am happy+proud how everything turned out. Huge thanks to everyone who contributed!

Turing Award goes to Charles Bennett and Gilles Brassard! Congratulations! amturing.acm.org

The Qalypso School on Quantum Science in Malta returns for its 3rd edition Aug 31 - Sep 4 this year! 🏖️ We have a great line up of lecturers covering Quantum Optimisation, Quantum Thermodynamics and Quantum Gibbs Sampling. Pre-registrations opens today at forms.gle/3NkMJ3Br9V8b... Do Share!

(left) how it started: -10°C and a snowstorm in my Austrian home village 🌨️☃️; (right) how it's going: +34°C and burning hot sunshine in Natal, Brazil ☀️🌴. It never ceases to amaze me how far modern airtravel can get us. Also, excited for our school+workshop in Natal 🇧🇷: www.iip.ufrn.br/en/events/qu...

Highlight of the day: a crochet workshop for our team at @jku.at. Featuring topology, sloths, tea, cookies and, most importantly, hands-on practice with hook and yarn. Go team!

This year's Quantum Computing Theory in Practice Conference (QCTiP) is scheduled for 04/20/2026-04/25/2026 in Oxford, UK 🇬🇧: qctipconf.github.io Talk submission deadline is just round the corner: 01/11/2026. Looking forward to many exciting contributions and a great time in Hogwarts🪄, aehm Oxford🎓.

Personal highlight: after 3 knee surgeries over the past years and a lot of physiotherapy lessons, I am finally back on the skiing slopes. 🎿🏔️⛷️ And it feels amazing! Huge thanks to all the expert care and dedication that made this possible. Some wounds can heal after all!

At our QUICK Quantum Computing Group, we’ve adopted the sloth as our group mascot, a QUICK reminder that good things take time! 🦥 To celebrate International Sloth Day last week, we raised funds and donated to the Sloth Conservation Foundation. Great initiative by Marwa Marso (last row center)!

(I/III) We're excited to announce a new tenure track opening! The position is called 'quantum informatics' and is affiliated with our QUICK group within the CS+AI division at @jku.at 🇦🇹. Application deadline is November 30th, 2025: www.jku.at/en/the-jku/w...

Fruitful crossover between Berlin, Germany, and Linz, Austria. @faehrmion.bsky.social -- MVP of this project -- discovered most of the shadow of the Hadamard test while spending time with our QUICK sloth team in Linz, Austria 🇦🇹.

In the shadow of the Hadamard test: Using the garbage state for good and further modifications journals.aps.org/prl/abstract... I am excited to see this improvement of the primitive of the Hadamard test in #quantumalgorithms in press in the PRL. We combine the unused output with shadow estimation.

In 2021, Robert Huang, myself & @preskill.bsky.social identified quantum state learning tasks that look hard, but become easy if you jointly process 2 copies. I have long wondered whether such challenges exist for c>2 copies. Turns out yes, there is an infinite hierarchy scirate.com/arxiv/2510.0...

🇦🇹🇭🇺 Austro-Hungarian reunion at the Hungarian Academy of Sciences. András Gilyén is probably one of the best quantum algorithm designers out there. He co-developed quantum SDPs, QSVT & Gibbs Sampling. No wonder he won an ERC! Happy that he also decided to return to Europe, and proud to be his friend!

💡 Mit einer großen Delegation ist Bundespräsident Alexander Van der Bellen im Mai nach Japan gereist. Mit dabei: die JKU Linz mit ihrem Quantenforscher Richard Küng. Österreich und auch die JKU wird sich auf der EXPO in Osaka präsentieren. 🎌 http://go.jku.at/n25m1 📸 privat

Um den Einsatz der JKU Forscher*innen im Bereich Wissenschaftkommunikation zu würdigen, wurden die Kepler Awards ins Leben gerufen. Das Interesse war enorm: Es gab mehr als 90 Einreichungen, die sich in vielfältigen Initiativen engagieren. Wir gratulieren alle Gewinner*innen!🏆 http://go.jku.at/n25l7

A short info videoabout MRI imaging @jku.at which combines two of my favorite things: quantum technology ('spins') and math of imaging ('Fourier transforms'). It also made a very real difference for my personal life when I had nasty knee injuries: www.youtube.com/watch?v=NBfb...

In the shadow of the Hadamard test: Using the garbage state for good and further modifications scirate.com/arxiv/2505.1... This work adds an unexpected twist to the Hadamard test by exploiting previously overlooked information.

www.quantumscience.at volunteered me to host my first proper workshop (~120 participants) at @jku.at. It really hits differently when you do not only welcome your peers at your academic institution, but also your hometown. We had a blast-furnace! @voestalpine.bsky.social steelfactory pun intended. 🇦🇹

Last week I had fun teaching quantum complexity at the kaleidoscope research school at CIRM, Marseille 🇫🇷🥖: (conferences.cirm-math.fr/3225.html. Amazing location, great atmosphere and, finally, enough blackboard space for a lecture of yours truly! 😋 Lecture notes are here: www.jku.at/fileadmin/gr...

Four Tenure-track positions in AI exclusively for female applicants at @jkulinz.bsky.social! Details available soon at www.jku.at/en/lit-artif...

A reminiscing article about our quantum music project 'the sound of entanglement' made it into one of Austria's most reputable newspapers - @derstandard.at. More than 3000 people attended, a truly unbelievable experience. Huge thanks to the entire team and to @ya-oeaw.bsky.social for publishing it!

Last fall I taught two big classes on **computational complexity** (left selfie) and **quantum computing** (right selfie). We had a blast! Lecture notes are here: www.jku.at/fileadmin/gr..., www.jku.at/fileadmin/gr.... It was a lot of work, but now I am happy+proud to share them. Feedback welcome!
