In this work we applied a quantum circuit treatment to describe the nuclear spin relax- ation. From the Redfield theory, we were able to describe the quadrupolar relaxation as a computational process in the case of spin 3/2 systems, through a model in which the environment is comprised by seven qubits and three different quantum noise channels. The interaction between the environment and the spin 3/2 nuclei is then described by a quantum circuit fully compatible with the Redfield theory of relaxation. Theoretical predictions are compared to experimental data, a short review of quantum channels and relaxation in NMR qubits is also present.
