I'm reading the part of the qiskit textbook that deals with this (https://qiskit.org/textbook/ch-quantum-hardware/error-correction-repetition-code.html) and so far it seems as though they're just protecting from errors using repetitions.
In the article they spoke a bit about detecting the errors using syndrome measurements, so I thought the next step would be correcting them....but then they went on to speak about lookup table decoder and majority voting to understand the output
So where exactly does the correcting of the errors (identified using syndrome measurements) occur? Can someone clear this up for me please
