| contents | We investigate how gravitational time dilation affects the coherence and entanglement dynamics of spatially separated qubits using open quantum systems theory. Unlike earlier works that consider only static or Markovian noise models, our approach incorporates phase damping, amplitude damping, and thermal excitation, along with a non-Markovian extension. By embedding gravitational redshift into the local decoherence rates, we demonstrate asymmetry in entanglement degradation and reveal the possibility of revivals in structured environments. Our findings have implications for relativistic quantum communication and space-based quantum technologies. |
