| contents | We reconsider a thought experiment that employs the entanglement of the gravitational field with position space quantum states as a means for faster-than-light signaling. We present a protocol that includes the excitation to a higher internal energy level to increase sensitivity to gravitational phase shifts. We report that the explanations why previous versions of the thought experiment remain causally consistent are insufficient to avoid any possibility for faster-than-light signals in this case. An alternative resolution to prevent faster-than-light signaling is most reasonably the requirement for a (near) relativistic treatment. One such effect could be a decoherence channel unobserved in a nonrelativistic treatment. |
