We perform a numerical study of the quantum interference between impurities in d-wave superconductors within a potential scattering formalism that easily applies to multiple impurities. The evolution of the low-energy local density of states for both magnetic and nonmagnetic point scatterers is studied as a function of the spatial configuration of the impurities. Further we discuss the influence of a subdominant bulk superconducting order parameters on the interference pattern from multiple impurities.
