Anyone else working with code and #AI agents feeling this fatigue each day after work? I have like 4-5 simultaneous agents running for different threads of work, cycling through them as the day goes -> reading and responding. This is "productive" but very exhausting - my 🧠 feels like a squeezed 🍋

If you are interested in #quantumcomputing and #chemistry here is a small nugget. A friend of mine has just published a paper on the arXiv (arxiv.org/abs/2608.11733) that shows the first double excitation operator implementation (QEB) with 12 CNOT gates - for years the record was 13. Enjoy

A 12-CNOT Double Qubit Excitation Gate

Effective implementation of high-level quantum gates is essential for practical quantum computing. To the best of our knowledge, we present the first reported 12-CNOT decomposition of the double qubit...

On this day 26 years ago, suddenly I had the very rough idea of a novel. The idea stayed with me. I worked on it. Obviously more off than on. But even the snail reaches the finish line in the end. essence.info bsky.app/profile/esse...

The quote 'Every country has the government it deserves.' is currently echoing in my brain over and over again. I am not a fan of the idea but yet there seems to be some truth to it. Why does it keep echoing? Well Orange-Utan for one - but also that the EU has again failed with Mercosur etc

Finally published : pubs.acs.org/doi/10.1021/... If you are interested in how to compute vibrational wave functions on a fault-tolerant #quantum computer, check this out.

For all attending the #SC25 conference. If you are into #quantum and #quantumcomputing for #chemistry/#compchem: Kvantify's Qrunch for chemistry on quantum computers just got publicly available: www.kvantify.com/blog/danish-... Come and drop by the AWS booth #2207 between 2pm and 6pm :)

I have just signed up for #SC25. Looking forward to visiting St. Louis and the scientific program, but also talking #HPC and especially #quantumcomputing with many of the world leading manufacturers.

After a long time in the making I am happy that this piece of work finally sees the light of day: Fault-tolerant vibrational structure calculations arxiv.org/abs/2508.16253 #compchem #compchemsky #quantum #quantumcomputing

I will soon advertise a call for a 2y-postdoc position in my group intended for a talented, motivated, and ambitious candidate to help develop new ways to promote bonds as kernels in the interpretation of chemical simulations.

Gave a talk in Copenhagen yesterday at a small scientific conference on quantum computing with great attendees. It was an interesting experience after so many years out of touch with "my field". Hope to deepen the interaction in the future. Below is the part of the presentation I am most proud of:

After a very long time it is finally peer reviewed and out: pubs.acs.org/doi/full/10.... The preprint (arxiv.org/abs/2408.11091) is from last August and (v1) not that different from the published version. For some reason I always get content-fatigue when it comes to the final touches.

"The bullshitter ignores these demands altogether. He does not reject the authority of the truth as the liar does [...] He pays no attention to it at all" - Harry G. Frankfurt in "On Bullshit"

Politics is a strange thing - and I feel I am missing a basic nugget of education here. Why is it that on a personal level it mostly does not matter where people come from and we get along just fine - but as soon as we start building and thinking in groups (tribes, countries etc) it turns to 💩

Now seems to be a good time to attract scientific talent from the US ... Europe should get their act together and invest in such individuals.

@bsky.app - Feature suggestion: Custom sorting of content into different feeds would be nice and in a way a obvious way to prioritize content - as an alternative to the opaque algorithms used by twitter (which some call X), fb etc

Are any of the #SC24 folks considering going to #ISC25? Last year was my first time at SC and it was fantastic. I am currently preparing a proposal for a BoF around #quantumcomputing to ISC and it would be great to connect with the #HPC community in Hamburg again.

Is there anyone working on an AI to replace CEOs? Many modern LLMs would probably do a decent job, given enough context. However, I imagine they would be hard to sell :D

For some reason Don Jr.s visit to #greenland has really kept me busy (and frankly up at night). There is so much wrong with it - I could go on ranting, but what really annoys me is that the "arrogant USA" has returned to the world stage - on steroids. But I guess that is what "America fist" means

I am currently collecting applications of #quantumcomputing - do you have pointers to your favorite results (preferably on hardware). My bias is of course towards #compchem, but anything counts really:)

Response by the DiffDock authors on the recent preprint by Jain and colleagues.

In #compchem applications of #quantumcomputing, IBM is currently using QSD (quantum sample diagonalization) as their workhorse. In some sense this is just encoding a wave function and then observing the frequency distribution afterwards. Why is that interesting?
