Squid Rings As Devices for Controlling Quantum Entanglement and Information
We model a SQUID ring coupled to one or two electromagnetic field oscillator modes, each component being treated quantum mechanically. We show that the external flux on the SQUID ring can be used to control th...

Manipulating Quantum Transitions in A Persistent Current Qubit
This paper discusses two methods for generating quantum transitions between energy eigenstates in a model persistent current qubit. The alternatives are compared and their advantages and disadvantages are cons...

Observation of Quantum Jumps in Squid Rings
In this paper we describe an experimental technique which we have used to probe the low lying energy levels of a quantum mechanical SQUID ring and to observe transitions between these levels.

Macroscopic Quantum Objects and their Interaction with External Environments
To gain some appreciation of why any quantum phenomena on the macroscopic scale should be regarded as potentially important to developments in quantum mechanics we have to look back to the origins of the subje...
