I have a couple of questions about entanglement and decoherence! 1. Sometimes you read that, strictly speaking, all electrons are entangled with one another. But can that be right?! Isn't it at least the case that electrons have to have interacted with one another in the past in order to be entangled? 2. I have been reading about how the environment can cause entanglement to disappear very quickly. Since molecules always occur in environments, doesn't that means that the spin entanglement that exists between two electrons in an atomic bond will likewise be destroyed? But how then do we explain how the atoms in the molecule stay bonded? Any thoughts much appreciated!
