Abstract
We examined properties of a Josephson-junction system composed of two-coupled Cooper-pair boxes (charge qubits) as a candidate for observation of quantum holonomies. We construct a universal set of transformations in a twofold degenerate ground state, and discuss the effects of noise in the system.
