Silicon spin qubits are susceptible to similar noise due to their small occupied area, and understanding noise correlations is essential. Although previous studies have shown high noise correlation in silicon spin qubits, the measurement is inefficient and disadvantageous from the viewpoint of integration. In this study, we focus on the dominant charge noise and analyze the current measurements of two quantum dots between adjacent channels to evaluate the noise correlation more efficiently.
