Glad someone took the time to debunk the (obviously nonsensical) claim that Bell inequalities could be violated w/o entanglement. It is astonishing (to say the least) that this claim was made by experienced authors & that it passed peer review in the first place, does not reflect well on the journal

A fun project with Seok Hyung, Jeongrak ( @perp-waterfall.bsky.social ), @nellynghy.bsky.social , and Paul Boes. We dusted off some old notes because there seemed to be renewed interest in what differentiates thermal operations from Gibbs-preserving maps.

Thanks to @phys.org.web.brid.gy for covering our recent work with @stotti-alex.bsky.social and @lvanluijk.bsky.social on embezzlement of entanglement in critical systems:

Congrats to Jake and all the collaborators for this fantastic work. They take the well studied problem of cooling quantum systems and use cool mathematics from group and graph theory to systematically characterize and solve that problem.

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...

Don't forget to submit your abstract for our conference in Dublin, August 2025! www.aspects-quantum.com/flqt2025

We are excited for Fundamental Limits of Quantum Technologies conference, Dublin, 25-29 August. Only three weeks left until the abstract submission deadline, don't delay! All details at www.aspects-quantum.com/flqt2025

Sms alot of people wanna go to Benasque QI than one can fit in the beautiful tiny village.

Having organised a bunch of stuff in Malta, I feel the urge to organise a straggler event on the island of Gozo.

If interested, fill this form so I can gauge interest - share!

We’re organising a conference in Dublin! Fundamental Limits of Quantum Technologies 2025 — everything from error mitigation on NISQ devices, through control constraints on complex quantum systems, to quantum thermodynamics and energetics, and much more! Abstract submission and registration open! 👇

Wrote up a little tutorial + review on higher-order quantum operations. If you love quantum channels, you can think of these as linear maps that act on channels themselves in manner fully consistent with quantum theory! I hope it helps future students / researchers! 🤗

Latest preprint from the ASPECTS consortium! arxiv.org/abs/2502.00096 Experiments by the amazing @naresgroup.bsky.social and theory by @mathsmire.bsky.social of @quitphysics.info We measured the entropy cost of generating and recording ticks in a microscopic clock

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.

Bonjour Grenoble! Nice to see the beauty of the alps in Austria stretches all the way to France 🏔️
Here to visit the QEI conf. and curious to learn how others think about thermo of quantum computation. Tomorrow I'll talk about work (arXiv:2402.00111) we did in Vienna. Come by if you are around.

Nice article about the history of the idea of entropy over the last 200 years. I'll have more to say about this in the new year 👀

Pretty cool to see some work we were involved in recognised by New Scientist as some of the 'wildest physics' they covered in 2024!
