A key step on the road map to solid-state quantum informa-tion processing (and to a deeper understanding of many coun-terintuitive aspects of quantum mechanics) is the generationand Manipulation of nonclassical correlations between differ-ent quantum systems. Within this framework, we analyze thepossibility of generating maximally entangled states in a sys-tem of two superconducting flux qubits, as well as the effectof their own environments on the entanglement dynamics. Theanalysis reported here confirms that the phenomena of suddenbirth and sudden death of the entanglement do not depend onthe particular measure of the entanglement adopted.
