I'm working on a research paper on Quantum Entanglement and came across something I don't understand. (I assume this goes here rather than in the homework forum because it applies to a topic rather than a problem. Sorry if I'm mistaken.) From what I've read, if two electrons are entangled, one will have an up-spin and the other will have a down-spin. However, there can be more than two electrons entangled (scientists have entangled three). With three electrons, there can't be just one with up-spin and one with down-spin, so what happens? Secondly, what happens if two electrons with the same spin are entangled? For example, two electrons, each with up-spin, are entangled--one should stay up-spin and one should switch to down-spin, correct? Yet if they are entangled and have negligible differences, there is nothing to determine which one switches to down-spin and which one remains up-spin. How does this work? Sorry if these are stupid questions, I am in 11th grade in high school so I have not yet had any quantum mechanics courses. Any help is appreciated. Thanks.
