I don't understand. If the two atoms are linked via entanglement, why are they also connected by optical fiber? if aiming a laser at the first atom will change its state, then shouldn't the state of the second atom change too at the same time? " That photon zooms along the optical fiber to other optical cavity containing the other atom." photon zooms? that means on the other side of the optical fiber, the second atom absorbs more than just one photon?
