The entanglement properties of the spin-2 field have only been recently studied.
We present some results for the entanglement properties of the linearised graviton in 4 dimensions.
The coefficient of the logarithmic term in the entanglement of gravitons across a spherical surface
contains a classical contribution due to the Gauss law in gravity. We present the details of how this classical contribution is evaluated and how the result is consistent with recent observations of edge partition functions of gravitons on the 4-sphere. If time permits, we briefly discuss the time dependent behaviour of entanglement entropy quantum quenches due to curvature excitations.
