We discuss the performance of two qubits with a transverse coupling affected by transverse low-frequency noise. In the adiabatic approximation, the system dynamics develops separately in two subspaces, with differing behaviors depending on the qubits' coupling strength and the noise amplitude. In one subspace, an optimal value of coupling is found, which minimizes the noise effects and leads to a slower signal decay.
