...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...

2026 Quantum papers!
Congratulations Quantum community! It’s hard to believe 10 years have passed and we’re en route to our 10-year founding anniversary in April 2026. On that occasion we wanted to announce ...

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

"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...

Entropic costs of the quantum-to-classical transition in a microscopic clock
We experimentally realize a quantum clock by using a charge sensor to count charges tunneling through a double quantum dot (DQD). Individual tunneling events are used as the clock's ticks. We quantify...

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 👇

Emergence of a Second Law of Thermodynamics in Isolated Quantum Systems
Novel bounds on the equilibration of observables in isolated quantum systems help resolve the apparent contradiction between the second law of thermodynamics and unitary evolution.

Optimal unitary trajectories under commuting target and cost observables; applications to cooling
The preparation of quantum states, especially cooling, is a fundamental technology for nanoscale devices. The past decade has seen important results related to both the limits of state transformation ...
