N2 - Quantum simulation results of superconducting correlations for strongly correlated electron systems are reported. An extended-type Hubbard model to take account of the role of oxygen sites in the CuO2 plane of high-Tc oxides is studied primarily. Superconducting susceptibility shows a tendency of quantitative enhancement at lower temperatures in contrast with the case of the single-band Hubbard model. It shows that a coupled two-band system, one with strong and the other with weak correlation, is favorable for superconductivity. A possible connection between superconducting and antiferromagnetic correlation is also discussed.
