Looking forward to seeing you there in a week, Richard!

Mmmh #qip2026 ...
(The map is awesome btw!)

The Cluster of Excellence ML4Q is offering fellowships to outstanding postdoctoral researchers on quantum computing and networking architectures based on solid-state physics, quantum optics, and quantum information science ml4q.de/ml4q-fellows...

100% agree. Especially since we have author IDs that are matched to the papers when they are claimed!

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🎓.

Has quantum advantage been achieved? Recently, I gave a couple of perspective talks on quantum advantage, one at the annual retreat of the CIQC and one at a recent KITP programme. I started off by polling the audience on who believed …

Dominik Hangleiter weighs in with an informative post about a much debated question: Has quantum advantage been achieved? This is the first post in a three-part series.

Have fun, Richard, and take care :)

I just received a paper for a Springer journal that was obviously LLM-generated, complete with non-existent theorems, missing proofs, and hallucinated references. The journal has double-blind review. You see the problem? Stone thrown, hand hidden. No one to name-shame.

Now published in PRX Quantum:
A robust control framework based on optimized pulse sequences enables faithful realization of arbitrary local Hamiltonians, scaling efficiently to hundreds of qubits.

Thanks for the nice article, I enjoyed the read. A comment: magic and entanglement are two distinct properties. Magic states don't need to be entangled, in fact the mentioned supply 'fueling' a quantum computer is given by individual single qubit states. The magic in ...

The list of accepted papers for #QIP2026 is now online at qip2026.lu.lv/programme/ac...

... but still pretty dear to us people caring about designs and magic :)

I think PxPxPxP would like to have a word

In our case, they changed the formulations of funding acknowledgements. These are typically dictated by the agencies, and deviating from that is highly discouraged. Why do they mingle with this at all?

Reminder of the preferred approach when sharing arXiv preprint links

A meme on how arXiv/quant-ph and scirate is currently flooded with QIP submissions. quant-ph is depicted as a city upon which three tidal waves of increasing height are collapsing. The smallest one is titled "< 8 Oct", the middle one "QIP papers 9 Oct" and the largest one "QIP papers 10 Oct".

Scirate will break today

QIP deadline. I expect the same (or even worse) tomorrow :)

I know that at least one submission was way ahead deadline (#280). Any last minute submissions @zoltanzimboras.bsky.social ?

@dulwichquantum.bsky.social

Very interesting work, thanks for the summary, Pieter! But you forgot the mandatory meme!

Are you a student or early-career researcher in quantum computing or quantum information? Then the following is for you.

We're organising a focused, community-driven conference at Leibniz Universität Hannover, hosted by Prof. Robert Raussendorf.

🗓️ Save the date: August 27–29, 2025

LLM?

From Barbara Terhal: On July 17-18 a small symposium "Dreams of Quantum" will be held in honor of David DiVincenzo's work and retirement at RWTH Aachen. The event can be attended by all via a Zoom link. www.quantuminfo.physik.rwth-aachen.de/cms/~bmmwed

Many thanks for the great work to my coauthors Lorenzo Grevink, @haferjonas.bsky.social, Jonas Helsen, Marcel Hinsche, Tommy Schuster, and Zoltan Zimboras. This work was started during the workshop on random quantum circuits 2024 in Amsterdam, stay tuned for the next one 2026 in Cologne!

No-go theorems for sublinear-depth group designs Constructing ensembles of circuits which efficiently approximate the Haar measure over various groups is a long-standing and fundamental problem in quantum information theory. Recently it was shown th...
