Working on LSD was fun! - Our paper on Localized statistics decoding (LSD) for qLDPC codes is now in print. LSD is a highly parallelizable, reliability-guided inversion decoder that exploits the clustering of errors. Think of it as a parallel version of OSD. www.nature.com/articles/s41...

Paul Hilaire and I are recruiting a PhD student to work on demonstrations of fault-tolerant protocols for near-term quantum hardware (photonics & cold atoms). The focus is on quantum error correction, low-overhead schemes, and actual implementation on hardware

Great work by the IBM Quantum team on Relay-BP, a BP-only heuristic decoder for general qLDPC codes. From a first look, the performance seems strong and further supports qLDPC architectures from a decoding-focused perspective. arxiv.org/abs/2506.01779

I recently created a simple Python wrapper for the Tesseract decoder for personal use, but I’ve decided to make it public in case others find it useful. Feel free to let me know if you encounter any issues! github.com/seokhyung-le...

There is now an official announcement: The TIB has archived the current status of the arXiv: blog.tib.eu/2025/05/14/p...

New AIP report discusses impact of funding cuts in physics & astro depts: “No one can be productive in a climate like this—it is the end of the US scientific and technical dominance in the world—we will not recover from this in a decade...”. ⚛️🔭 physics.aps.org/articles/v18...

Ok, heute ARD-Brennpunkt zur AfD, auf einen der Gäste kommt ihr nie. Richtig, Tino Chrupalla. Vor 80 Jahren hätte der zumindest auf der Anklagebank gesessen. Woher diese unbändige Lust, weiter mit Nazis zu reden? Ist es Masochismus? Erinnerungskultur tm? Oder vermisst ihr einfach eure Omas und Opas?

Next up in session A is Lucas Berent telling us about LSD, a popular topic in Berlin.

This past week, I received a second stop work order on one of my grants. This now means that we can no longer spend on *two* of my major grants. Several of my group members will now graduate earlier than expected, I am looking into being a consultant for the summer, and students will do internships

Dass ausgerechnet die CSU-Politikerin Doro Bär, die noch vor wenigen Jahren den menschengemachten Klimawandel leugnete, jetzt neue Forschungsministerin werden soll - ein Job, bei dem es ganz besonders darauf ankommt, der Kraft der Wissenschaft zu vertrauen, ist m.E. hochproblematisch.

Typing away on my PhD thesis - no matter where I go next, the views from my office will be hard to beat, unfortunately.

When we wrote the theory proposal for the dissipatively stabilized squeezed cat qubit, we got into an argument with the copy editors of the journal. I had a strong opinion against calling it „cat state qubit“ (as no one does) which got so far that we almost had to add a disclaimer, see the mail

I think it would be a good time to reinstantiate the mirror network for the # arXiv. It’s an essential piece of the global research community in math, physics, computer-science and adjacent fields. Under the current circumstances it should not only be hosted in the US. #quantum #math #physics #cs

First realization of a dissipatively stabilized squeezed cat qubit (a slight variation that we called a moon cat 🌛 actually), it was super interesting to work on this with experimentalists! arxiv.org/abs/2502.07892 My two key takeaways ⬇️⬇️

I’m super excited to see the experimental realization of a variant of the dissipatively stabilized squeezed cat that we proposed! Congrats to Alice & Bob and everyone else involved Especially great to see that it comes with similar performance gains as promised by the theory arxiv.org/abs/2502.07892

@adamwills1.bsky.social updates is on his recent work with collaborators on constant overhead magic state distillation and quantum codes with addressable and transversal non-Clifford gates #Coogee25

Armanda Quintavalle giving a great introduction to Quantum Tanner codes and talking about on going work of finding small~ish examples with good properties. #Coogee25

@mattmcewen.bsky.social kicking of #Coogee25.

Soon, @christophe.vuillot.info and I will be restarting the online QASAR seminar series on quantum error correction! Please let me know if you would like to give a talk :)
