so Zapata patented QIR... the project that got started as a collaborative + open standard by multiple orgs (none of with was zapata). First, why were they granted this patent, and second... wtf Zapata, and third, I thought they turned into an AI company? investors.zapataquantum.com/news-release...

Me: Immediately buying a train ticket to Germany.

It's not easy to work for Jeff Bezos these days. Sending prayers to John Preskill @preskill.bsky.social, Fernando Brandao and others at Amazon Quantum, and hoping it won't go down like Washington Post. 🙏 Luckily quantum is a priority for Trump (unlike free press)! www.theguardian.com/media/2026/f...

Every paper should be announced like this! 🤘

When your butt slides into DMs with Dulwich without you being aware of it.

Just LOVE the "Advanced Quantum Algorithms" lecture notes of Stacey Jeffery!!! homepages.cwi.nl/~jeffery/not... Everyone teaching quantum computing should read this paragraph out loud to their students! homepages.cwi.nl/~jeffery/not...

Next time you're making a wish on a shooting star, it might actually be a quantum satellite burning up in the atmosphere. 🌠

You too can go from zero to Kitaev in 3 weeks! www.coursera.org/learn/quantu...

Are these ice cream flavours or finance terminology? arxiv.org/abs/2602.03725

That’s nothing: Topological qubits have only reached the same point that the Catholic church did 2000 years ago. (Made up stories and claims of miracles).

My TQC submission.

Looks like we'll be having some trouble deciding how fast our quantum internet connections actually are. arxiv.org/abs/2601.22471

One more hour left till the TQC deadline!

Once you're done with your TQC submission, give yourself a small reward and check out the YouTube comments section of the MELANIA trailer. It is a goldmine! www.youtube.com/watch?v=dxXJ...

The Dulwich award for the best poster setup at #QIP2026 goes to Kotowski and Oszmaniec!

As usual, Dulwich Quantum is placing a bid to host #QIP2028 in Dulwich, South London! Don't forget to vote for us!

5 lessons learned by John Watrous @johnwatrous.bsky.social in quantum education.

What the hell? @dulwichquantum.bsky.social #QIP2026

It may be cold in Riga during #QIP2026, but the fascism on display in the US is way more chilling.

Fun fact I learnt preparing my condensed matter lectures for this semester: Arnold Sommerfeld was nominated 84 times for the Nobel prize in physics, but never won. Interestingly, despite his lifelong Nobel prize disappointment, Sommerfeld never threatened to invade Greenland (as far as I know).

Love the rock concert vibes of #QIP2026!

Bless your soul! #QIP2026

Every week you get a new chance to finish your paper by the end of the week.

It's funny how the first speaker today was implicitly saying that quantum advantage has been achieved while the second one is saying that it has not. #QIP2026

"If you can solve hard problems, you can solve easy problems." --André Chailloux at #QIP2026

"Easy-peasy!" --Ludovico Lami @ludovicolami.bsky.social at #QIP2026

"We are a group of quantum scientists who oppose the ongoing militarization of our societies and the use of quantum research for military purposes." disarmquantum.com Manifesto: arxiv.org/abs/2601.14282 Here's just one example: "Quantum technology for military applications" doi.org/10.1140/epjq...

Me on my way to #QIP2026 today.

Advice for Jens Eisert. doi.org/10.1038/d415...

Apparently there's a "Quantum Escape Room" in Eindhoven. nextnature.org/en/museum/qu... Whoever invented it: Imagine being locked in a room for 4 years and you need to solve quantum puzzles to get out... Quantum PhD student: Yeah, that's how my whole life feels like...

Can't the Greenland thing wait for a couple of weeks? If Trump takes Greenland now, Putin might consider taking Latvia during #QIP2026.

The real reason why you need to submit your slides before the start of #QIP2026 is so that during the conference you have time to work on your #TQC2026 submission.

What a loser.

Trying out a new group meeting format where first everyone updates each other on government crackdown of protests in their home country.

Are you giving a talk at QIP this year? Here is a thread of pro tips from Dulwich.🧵 1. The most important thing is to prepare yourself mentally. Remember, no matter what happens on the stage, you go on!

Come over I will give you a coffee if you wanted to publish in @nature.com or @science.org but decided not to

But can it be exchanged for a FIFA Peace Prize?

Stefan Knecht has written up a nice summary of Garnet Chan's new paper "No, FeMoCo hasn’t been entirely solved but for its gold-standard active space model (the model QC folks have been looking at), there is now a classical benchmark which provides an excellent baseline for any quantum work." 🧵👇

6/6 ... this work gives us a compelling classical benchmark which will serve as excellent baseline for any quantum work. Yet, world hunger won’t be solved by that work "just yet" but, and that’s the good news, it tells us more about the computational framework and vast(!) resources needed to do so.

The promise of solving the electronic structure of FeMo-co has long been central to the narrative that quantum computers will one day solve world hunger. Now we can finally put the "solving world hunger" part to test since Garnet Chan just solved FeMo-co *classically*! arxiv.org/abs/2601.04621

“No quantum symbols if you don’t finish your numerals!”, I told my 4yo daughter.

Wasn't expecting that this would be fulfilled so soon. Only 360 more days to go this year...

The difference between classical computers and quantum computers is like the difference between normal "Jingle Bells" and "Mongolian Jingle Bells". [sound on] www.youtube.com/watch?v=FEu7...

Quantum challenge for 2026: keep a logical qubit alive longer than Zohran Mamdani can smile! 😃
