I used this method to initialize classical data in a circuit. I would like to know what's under the hood and the complexity of this procedure, but I can't find anything on the internet which suits my thoughts.
The procedure is this: https://qiskit.org/documentation/locale/bn_BN/stubs/qiskit.circuit.library.StatePreparation.html
I tried to read the reference, but I'm from a computer science degree and it is over my competences :(, if there is someone which could explain it in simpler terms, I am open to chat.
Thanks to all
