We model the apex of the cavity tip and substrate as a conducting sphere and a half-space bounded by a plane. We solve the Laplace equation—we work in the quasistatic approximation—for this geometry using an infinite series of image charges. The magnitudes and positions of these image charges are determined by a system of finite-difference equations.
We describe application of this solution to the modeling of multiqubit systems in the presence of dissipation and noise. This model reveals the presence of certain collective behaviors of the qubits including the existence of dark states.
