I don't understand, what is the purpose of measuring electron spin for your various atoms? Electrons are in a probability cloud, you need to scan/replicate the atomic structure, not measure the electron spin of your atoms. Doesn't really make sense for me, do you have something particular in mind or?

Do you? I already said what I have in mind. particles are not indistinguishable and "scanning" objects without destroying them not possible in this reality
