    • 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 ...

    • Stochastic resonance phenomena in spin chains 

      Rivas, A.; Oxtoby, N.P.; Huelga, S.F. (2009)
      We discuss stochastic resonance-like effects in the context of coupled quantum spin systems. We focus here on an information-theoretic approach and analyze the steady state quantum correlations (entanglement) as well as ...
