This model introduces custom asymmetric depolarizing noise for both single- and two-qubit gates depending on whether operations are global, local, or part of a CZ interaction. Since the model assumes all atoms are in the entangling zone, errors are applied that stem from application of Rydberg error, even for qubits not actively involved in a gate operation.

Note, that the noise applied to entangling pairs is correlated.
