In this paper, we introduce a new quantum noise mitigation protocol that operates by monitoring how the parameter that describes the channel quality changes through test qubits and using the information obtained to make decisions on how to correct the information sent. This strategy has allowed the development of a protocol that yields good results for both low-noise and high-noise channels. To validate the protocol’s functionality, state-independent fidelity and coherence were calculated, showing that our protocol performs better considering the mean values of the calculated fidelity, despite demonstrating a decrease in coherence in some specific scenarios. Even so, generally speaking, our protocol is particularly efficient in situations where the codes already presented in the literature exhibit some flaws.
