We study the relation between Chern numbers and quantum phase transitions (QPT) in the XY spin-chain model. By coupling the spin chain to a single spin, it is possible to study topological invariants associated to the coupling Hamiltonian. These invariants contain global information, in addition to
## Abstract We will show how geometric phases, i.e. phases which appear when a system undergoes a cyclic adiabatic evolution, can find useful application in fault tolerant quantum computation. A particular setup based on coupled superconducting nanostructures will be described
