The entanglement swapping protocol is analyzed in a relativistic setting,where shortly after the entanglement swapping is performed, a Bell violationmeasurement is performed. From an observer in the laboratory frame, a Bellviolation is observed due to entanglement swapping taking place, but in amoving frame the order of the measurements is reversed, and a Bell violation isobserved even though no entanglement is present. Although the measurementresults are identical, the wavefunctions for the two frames are different---one is entangled and the other is not. Furthermore, for boosts in aperpendicular direction, in the presence of decoherence, we show that a maximumBell violation can occur across non-simultaneous points in time. This is asignature of entanglement that is spread across both space and time, showingboth the non-local and non-simultaneous feature of entanglement.
