   Noise models can be categorized as those that cause the state to leave the maximally symmetric subspace and those that do not. The former include single-spin errors akin to qubit Pauli noise. The latter include collective rotations or decays.
-  A particular error basis of interest consists of the spherical tensors \cite{arixv:2304.08611}.
