A game of surface codes demo (#1355)

P0 Game of Surface Codes Demo 2025 Q2 [sc-87600]

open question:

- [x] ~~do I understand it correct that single X and Z measurements are
free, but joint measurements cost 1 🕒?~~ >> yes
- [x] ~~What does it mean that the error probability of the distillation
of 15 faulty magic states with $p$ leads to a faulty magic state with
probability $35p^3$, yet, the probability of failure is $(1-p)^n$? 🤔~~
>> p is the infidelity of the state, and $35p^3$ is the infidelity of
the distilled state. The success chance of not having an error is
$(1-p)^n$
