Quantum Superposition: Is It Limited or Unlimited?

[Allen_Wolf]

Is Superposition of the position of particle limited to a certain area or is it unlimited?
Like, an electron: Can an electron on Earth be like in Jupiter or proxima centauri due to superposition? I mean, such vast distances?

It can, but the probability is too small to even think about it being so far away.

In theory, yes. But I don't see how you could achieve that experimentally. And such a superposition would be extremely sensitive to decoherence: the smallest interaction of the electron with something on Earth or on Jupiter would result in the electron being here or there.
