2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/23072We 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 two-fold degenerate ground state, and discuss the effects of noise in the system.RevTeX4, 5 pages, 3 figures, minor changes requested by Phys.
