but wouldn't that make the problem of sending information a technological restraint? If you could control the quantum state of one atom you could then use it to send information. So I'm assuming controlling the quantum state of an atom is impossible?

something that has bugged me ever since i thought about it. Does quantum entanglment (when used to send a signal) violate causality?
