  We propose a complete, quantitative quantum computing system which satisfies
the five DiVincenzo criteria. The model is based on magnetic clusters with
uniaxial anisotropy, where standard, two-state qubits are formed utilizing the
two lowest-lying states of an anisotropic potential energy. We outline the
quantum dynamics required by quantum computing for single qubit structures, and
then define a novel measurement scheme in which qubit sates can be measured by
sharp changes in current as voltage across the cluster is varied. We then
extend the single qubit description to multiple qubit interactions, facilitated
specifically by a new entanglement method which propagates the controlled-NOT
(C-NOT) quantum gate.
