    "abstract": "We propose a new simulation computational method to solve the reduced BCS\nHamiltonian based on spin analogy and submatrix diagonalization. Then we\nfurther apply this method to solve superconducting energy gap and the results\nare well consistent with those obtained by Bogoliubov transformation method.\nThe exponential problem of 2^{N}-dimension matrix is reduced to the polynomial\nproblem of N-dimension matrix. It is essential to validate this method on a\nreal quantum",
