Abstract
We use a discrete-field model for the quantum evolution of distributed superconducting circuits to calculate the effective capacitance for a radio-frequency-SQUID magnetometer: a large-capacitance superconducti ng ring containing an ultra-small-capacitance weak link. We demonstrat e that the self-capacitance of the weak link can dominate the behaviou r of the circuit.
