Question on entanglement

  1. Apr 3, 2009 #1
    Whenever i read or watch something on entanglement all they seem to talk about is the spin states of electrons. And i am confused, does whatever happen to one, the opposite happens to the other or can the same thing happen to both due to entanglement. Does entanglement go further than spin states, say for example if one electron is given energy, would its entangled pair electron gain that same amount of energy (or lose what the other gained)? And what about orientation like if one electron's probability density is shifted left will its entangled pair electron experience the same spacial shift to the right (or left as well)? thanks for your responses in advance.

    Yes, entangled particles - be they electrons or the more common photons - share other property combinations than just spin states. Frequency, momentum, position, etc. are also related. They can be entangled in a variety of ways depending on the experimental setup, so there is not one absolute answer. But the general rule is that that a single wave function describes non-commuting properties, and it is often convenient to think in terms of "what happens to one happens to the other". But no-one actually knows what is going on beneath the hood, even though the theoretical predictions are realized experimentally.
