If I have two electrons in the ground state of a helium atom, then one is spin up and the other is spin down . And there is no way of knowing which spin state each electron is until I measure it. So when I measure one electron to be spin up does this instantaneously make the other one spin down? Or if this doesn't work with the helium atom let's use a neutral pi-meson that decays into and electron and positron .
I have studied QM a little bit and any input will be much appreciated.
