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.

For large chains (>500 repeaters), global policies boost SKR by two orders of magnitude.
In some regimes, they make secret communication possible when local ones yield none.

All this introduces noise, which can be mitigated through entanglement distillation (EPP): turning many noisy EPR pairs into fewer, high-fidelity ones.
The question is: when to distill?
Too early - we waste good EPR pairs; Too late - noise kills us.

Quantum communication over large distances is hard due to photon loss, which grows exponentially with distance. Quantum repeaters solve this by dividing the channel into short segments, entangling neighbors, and recursively performing entanglement-swapping.

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. 🔑

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.

I believe so, though he uses different language and doesn't even use the word "Hadamard" there..
I'll also note that the LLM did reference that other paper mentioned above (based on the stack overflow thread) but I did not find the explicit name there.
