Classical purification of noisy Pauli-product states recovers magic and entanglement, with a noise floor that depends on when those resources are generated and on which circuit state is chosen.
In this next experiment, magic and entanglement is increased by adding Pauli exponentials, rather than sweeping the parameter angles in the circuit
