Congratulations, Dr. Xuereb! 🔥🧊🖥️👹

...okay back to serious papers, starting with the field of many-body physics. In this new preprint, Julia, Nicky, Pharnam, and Giuseppe provide new optimal entanglement witnesses for various many-body thermal settings: arxiv.org/abs/2604.01157

We talk a lot here about weird quantum things, from conceptual foundations questions to technological challenges. It's easy to be confused by it all, so here's Phila from our group giving a TEDx Talk at TU Wien last year on demystifying quantum physics! www.youtube.com/watch?v=pJkO...

Celebrate with us Quantum's approaching 10 year anniversary in 2026 with the publication of the 2026th paper! Do you know which paper that is? quantum-journal.org/2026-quantum...

10 years after its founding, driven by the energy, enthusiasm, & dedication of the community @quantum-journal.bsky.social quietly published paper #2000 some days ago. At least I think this is a big deal, big shout out to the founders & all authors, reviewers, editors, board members & contributors!

From one tick to the next, small timing uncertainties in clocks usually add up because of the independence of errors. Using fermions tunneling through a quantum wire as clock ticks, we found a way to build a clock where errors cancel out rather than accumulate. arxiv.org/abs/2601.10785

Very happy to see our latest work out in PRL doi.org/10.1103/5rtj... and highlighted by both @apsphysics.bsky.social Physics and @physicsworld.bsky.social Small thread below 🧵⬇️

"40h pro Woche arbeiten. Das ist doch weniger als ein Viertel! Da geht doch mehr!" Man hört das Argument von Wirtschaftstreibenden, jetzt auch vom deutschen Kanzler. Das Missverständnis dahinter: Viel arbeiten ist in erster Linie ein Privileg - das für viele einfach außer Reichweite liegt (Thread)

What started as informal discussions on the Danube beach in Vienna during QTD2023 has been published at last. Trying to come up with an experimentally feasible quantum clock we came across a rich model – the ring clock – that overturned a common wisdom in the community. doi.org/10.1038/s415...

🔥 🕰️ Read our new paper on the thermodynamics of clocks 🔥🕰️https://arxiv.org/abs/2502.00096 @mitchison.bsky.social @entangledanarchist.bsky.social

Now that our recent work on the emergence of a 2nd law of thermodynamics in isolated quantum systems has been published, I thought it may be a good opportunity to share some animations outlining the intuition for the principle behind it. doi.org/10.1103/PRXQ... See thread below 👇

This is now out in the journal Physical Review X Quantum! Super excited to be able to share this piece of work with everyone. I'm incredibly proud of it journals.aps.org/prxquantum/a...

New preprint! Here QuITters Pharnam and Fabien look at optimal quantum thermodynamic resource costs for state transformation processes such as ground state cooling: arxiv.org/abs/2412.07291

Cool article and video from ORF talking about our work in free-space quantum key distribution (auf Deutsch!) noe.orf.at/stories/3280...

In addition to research work, many members of our team do outreach and science communication. Here's a new article by QuITter Phila for the FWF on how quantum technology is being used in an ESA mission to Jupiter! (Also available in English) scilog.fwf.ac.at/magazin/jupi...

Hello science/physics/quantum blueskyers! We're the theory division of TU Wien's Atominstitut in Vienna. We do Quantum Information and Thermodynamics, as well as Q. foundations, computing, optics, many-body physics & more! Looking forward to connecting with other keen physics nerds here 🤓🧑‍🔬👩🏽‍🔬⚛️
