=== Sharing ===

After the preparation of the Bell state <math>|\Phi ^{+}\rangle</math>, the qubit denoted by subscript ''A'' is sent to Alice and the qubit denoted by subscript ''B'' is sent to Bob (note: this is the reason these states have subscripts). At this point, Alice and Bob may be in completely different locations, which might bean veryunlimited distantdistance from each other.

There may be aan longarbitrary period of time between the preparation and sharing of the entangled state <math>|\Phi ^{+}\rangle</math> and the rest of the steps in the procedure.
