Two measurements on one electron at nearly the sametime but different place

Hi,all. My problem is:

viewed theoretically.

The probability of finding an electron is none zero in everywhere.

experiments:

observer1 found the electron in positionA at t=0,

observer2 is at positionB which is L (distance) away from positionA, then at t<L/c, observer2 opens his microscope try to find that electron.

What if repeat this experiments many times until observe2 found it? wh=ould this really can happen?

PS: After observer1 found it, he ''put'' the electron back in order to reverse the collapsed wavefunction. Also, use electron is for the sake of the example, so don't say the electron can not be labeled, I could use someother particle instead.Thanks in advance

.Yes, it is possible for observer2 to find the electron in positionB if the experiment is repeated many times. This is because, fundamentally, electrons are not localized particles and exist in a wave-like state. As such, it is possible for an electron to exist in multiple places at once and, as a result, for observer2 to find the electron in positionB. However, it should be noted that the probability of observer2 finding the electron in positionB will depend on the initial wavefunction of the electron and the distance between positionA and positionB.
