  • Numerical analysis software development and theoretical analysis of superconducting circuits

    We have developed numerical analysis software for basic research on circuit quantum electrodynamics. We also performed theoretical analysis to clarify the characteristics of superconducting circuits.

    This numerical analysis software calculates the distribution function and calculates and outputs physical quantities such as specific heat when the Hamiltonian parameters of a superconducting circuit are entered.

    In the theoretical analysis, parameters were added to the equations used in the numerical analysis to increase the degrees of freedom and provide a more general derivation.
