One of simplest and most widely used error model in working with quantum circuits is the Pauli Twirling Approximation (PTA). Restricting ourselves to analysis of free dynamics of qubits we show explicitly how application of PTA is equivalent to ignoring most of the quantum back action of the system and give a general argument as to why this approximation leads to low logical error rates in fault tolerant stabilizer circuits as compared to other quantum channels. We provide numerical evidence that PTA's performance in modeling noise gets worse as number of qubits increase.

Limitations of Error Model Approximations in Quantum Network Simulation
Simplified error models such as Pauli twirling lead to severe discrepancies, including under/over-estimation, measurement dependencies, and fidelity oscillations, in iterative quantum network protocols.
