“…Finally, instead of depending on , the electric and magnetic field observables now depend on , i.e., they depend not only on the position but also on the amount of time the observer has been accelerating in space and on their acceleration. Most importantly, Equation (76) can now be used as the starting point for further investigations into the quantum optics of an accelerating observer [ 5 , 36 , 46 ], and is expected to find immediate applications in relativistic quantum information [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 69 ].…”
