Abstrakt:	We discuss the behaviour of a superconducting weak link ring coupled to a radio frequency tank circuit. We show that with the weak link acting quantum mechanically to connect different winding number states of the ring together two limiting regimes of behaviour are discernible. In the first, SQUID (Superconducting Quantum Interference Device) magnetometer, limit nearest neighbour winding number transitions dominate. In the second limit, which forms the basis for a quantum voltmeter conjugate to the SQUID magnetometer, all possible winding number transitions need to be considered. [ABSTRACT FROM AUTHOR]
