    • Probing a composite spin-boson environment 

      Oxtoby, N.P.; Rivas, A.; Huelga, S.F.; Fazio, R. (2009)
      We consider non-interacting multi-qubit systems as controllable probes of an environment of defects/impurities modelled as a composite spin-boson environment. The spin-boson environment consists of a small number of ...

    • Topological order following a quantum quench 

      Tsomokos, D.I.; Hamma, A.; Zhang, W.; Haas, S.; Fazio, R. (2009)
      We determine the conditions under which topological order survives a rapid quantum quench. Specifically, we consider the case where a quantum spin system is prepared in the ground state of the toric code model and, after ...
