Abstract A protocol of quantum dense coding with gravitational cat states is proposed. We explore the effects of temperature and system parameters on dense coding capacity and provide an efficient strategy to preserve the quantum advantage of dense coding for these states. Our results may open new opportunities for secure communication and insights into the fundamental nature of gravity in the context of quantum information processing.
