Hello.

I have a question suppose we have two entangled electrons , now we take them a sufficiently large distance away from each other so that the EM (light) wave would have to travel a certain distance/time.When one electron is measured at one place and the other at the other place they botch can then simultaneously know which one the other ones has.

Now I imagine you could not send information with many entangled electrons as when upon measurement you can't predetermine the spin of the first electron so you can't for the second one too only when the first one is measured then you can know the second one.

But if we would have multiple let's say 10 electrons entangled in 5 pairs.Now Alice is at one end and Bob at the other and they have wrote a code book in which it says that measuring the first electrons is A and the second B and the third corresponds C.

Now they both have a copy of this book Now Bob at his end can measure let's say the second electron first so Alice now sees that the second electron is revealed for her as Bob has measured it already and so Alice can write down the first letter B, then Bob decides to measure the third one and Alice writes down C and then A.

Now because in entangled particles when one is measured the spin of the other is know at the very instant but when large distance away could this then be a faster than light communication ?

If it would happen randomly I guess no, but in this case they both have agreed on a code and the code is not in terms of particle spin as you can't predetermine it but rather the code is about particle order say which one comes first which second.?

Just like typing on a keyboard but under every key there is a entangled electron with it's given number of order, at the other end there is a display which lights up certain letters that correspond to certain keys which were pushed and under them were certain electrons.

I hope I explained the scenario as good as I could.
