Bought 2 cappuccinos, guy at the counter “the one marked with an ‘x’ is the regular one”. Me: dude, just write which is which, I won’t remember the 1-bit encoding in 5 minutes.

Probably me if I were to work at Nasa.

People take for granted the fact that mangos are so delicious, but most don’t know that every logical mango is made out of many physical mangos.

When you transverse a graph and forget to update the ‘visited’ list.

*son asks me to text mommy asking when she is coming back* me: ok, I'll let you know if she answers. go to sleep now. son: will you let me know if she doesn't answer? me: but... it's the halting problem. son: ? me: never mind, son. go to sleep.

Excited to share my first paper (w/ Michael Ben-Or)! Quantum repeater protocols must decide when to perform entanglement-distillation - but should that decision be local or global? We find that global policies can make or break secure communication. 🔑 1/8 arxiv.org/abs/2510.06737

“I know it sounds woo” 🤣

Just published a Stim implementation of the [[16,4,4]] Tesseract code - the one used in Microsoft+Quantinnum's QECC experiment last year. Simulation can be used to quickly benchmark the code under various parameters. Contributions are welcome. github.com/DeDuckProjec...

Just defended my thesis 😱

Is there anything more suspenseful than running a simulation when you don’t even know if the code you wrote is correct?

Overheard people at the office talking about Poisson variables. Turns out they were talking about croissants. 🤦🏻‍♂️

I didn't say it was measurement back-action. It wasn't measurement back-action. XXXX and ZZZZ do commute.

That feeling…

I’ve created an interactive simulation of the Quantum Entanglement Distillation process. Entanglement distillation (or purification) is a central operation in quantum communication. Two parties generate many noisy EPR pairs, and then transform them... deduckproject.github.io/epp-demo/

The Weizmann Institute was also hit in the missile attack and Life Sciences buildings damaged. the New York Times reported that "laboratories caught fire."

I’ve implemented a liquid-glass filter with pure CSS and no JS. Code in the comments

Surprise stabilizer formalism on my commute

At the end of a fellow quantum student’s wedding, we formed a circle around the bride and groom, swinging from side to side, out of sync. All I could think of was how appropriate it was that we were simulating the 1d Ising model.

Tell me you’re not doing quantum without telling me you’re not doing quantum… 😕

Claude 3.7 tried to fix my test by creating a dedicated flow in the failing function :(

I found some (minor) inconsistency in a 20+ year old paper by a prominent researcher. He agreed that there’s an issue, but since the paper is old and the issue is minor - I don’t expect him to correct it. It would’ve been cool if I could just open a pull request and fix it myself, like on Github..

Street cryptography. Nice.

Finally, 2^8.224 makes so much sense!

Do “Ghiblified” images have enough information to recreate the original photos (faces in particular) they were derived from? I saw a claim saying Ghiblifying an image is a good way to share a scene without exposing your face. I am not sure its correct, though.

In Hebrew, an ion trap is spelled exactly as pigeon trap. Therefore, googling ״מלכודת יונים״ (Mal-ko-det Yo-nim) gives the following amazing result (this is not edited in any way).

My 7yo asked what my thesis is about. How do you explain quantum repeater protocols to a 7yo? I said it was kinda like a triple-jump game: Where there are 3 sticks and you have to jump across the next one every time. Now, I told him to imagine there are many more sticks >

Humans: pursue relief from uncertainty (presumably) Quantum stuff: hi

Whatsapp now supports code snippets but still doesn't support LaTeX.

Some cryptographic thoughts on breaking 4-digit locks (e.g for lockers) Assuming most people scramble their code after locking to make sure each digit is scrambled, i.e not the code digit. This gives attackers information on the code if they observe multiple scrambles (not a lot!). On the other hand

I’m a simple man. I see something I don’t understand in quantum computing, I wait for Scott Aaronson’s take on it.
