    "abstract": "We calculate the geometric phase for an open system (spin-boson model) which\ninteracts with an environment (ohmic or nonohmic) at arbitrary temperature.\nHowever there have been many assumptions about the time scale at which the\ngeometric phase can be measured, there has been no reported observation yet for\nmixed states under nonunitary evolution. We study not only how they are\ncorrected by the presence of the different type of environments but also\nestimate the corresponding times at which decoherence becomes effective. These\nestimations should be taken into account when planning experimental setups to\nstudy the geometric phase in the nonunitary regime, particularly important for\nthe application of fault-tolerant quantum computation.",
