  We investigate how resourceful gravitational cat states are to preserve
quantum correlations. In this regard, we explore the dynamics of gravitational
cat states under different situations such as thermal, classical stochastic,
general decaying, and power-law noisy fields. In particular, the one-way
steerability, Bell non-locality, entanglement, and purity in two qubits are our
main focus. We also address the weak measurement reversal protocol on the
dynamics of quantum correlations and purity of the state. Our results show that
the gravitational cat states have a reliable and better capacity to preserve
quantum correlations and remain one of the good resources for the deployment of
quantum information processing protocols.
