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 superconducting ring containing an ultra-small-capacitance weak link. We demonstrate that the self-capacitance of the weak link can dominate the behaviour of the circuit.

In this paper we consider from a theoretical viewpoint the interaction between a single macroscopic quantum object (a SQUID ring) and a classical circuit apparatus (a radio frequency resonant circuit). We demonstrate that chaotic solutions exist for this coupled system over a wide range of parameters and that this chaotic behaviour is determined by the quantum state of the SQUID ring.
