For a little bit of light in these trying times, I present to you: quantum memes! These are made by my Physics 438a class for extra credit on their midterm (which they are taking at this moment). As always, I take all credit for good memes and no blame for bad ones.

Any high level but technical explanations of DeepSeek that doesnt talk about nvidia stock out there? How did they build something seemingly competitive / superior with much fewer means?

We recently released a software package to optimize IQP circuits that scales to millions of qubits and gates. Our main motivation was quantum machine learning (paper on the way!), but we believe there could be many other applications. arxiv.org/abs/2501.04776 github.com/XanaduAI/iqp...

Do you remember the feeling when you finally fully grasped SVD and realized your linear algebra powers have no limits now? You can re-live that moment by learning about the KAK decomposition for the unitary group! pennylane.ai/qml/demos/tu... awesome summary by @dwierichs.bsky.social

Seeing our software and resources be used by other researchers and practitioners in the qc space gives me extreme "academic pride", for a lack of better words 🥲  Here's to more well-documented code in 2025

I can do a computation on my smartphone in a few seconds that would take the Antikythera mechanism longer than the age of the universe. Therefore we must live in a multiverse □ (or at least my smartphone lives in one)

History doesn't repeat - but sometimes it rhymes. In the 2010s, tiny dev teams built products w massive impact. A company with just 13 developers served 30M users. In 2024, a company with just 15 developers is serving 25 million users. Bluesky deepdive: newsletter.pragmaticengineer.com/p/bluesky

That whole septillion years bit is so misleading and prone for misinterpretation, I'm not even mad people outside the academic bubble take it the wrong way (though the confidence of some people with their hot takes is honestly mind-boggling and hilarious)

TFW *gets error message* *checks code* code seems fine, let's run the same code again *gets same error message* *surprise* 🤔

I think we can slowly start to call X, formerly known as Twitter, X, and BlueSky, Twitter

Are there already established de-facto standards for quantum compilation passes? (FT / NISQ) Stuff like TODD, ZX full_optimize, ... ? What else?
