Trace distance and linear entropy of qubit states: Role of initial
qubit-environment correlations    [PDF]

Jerzy Dajka, Jerzy Luczka

The role of initial qubit-environment correlations on trace distance between two qubit states is studied in the framework of non--Markovian pure dephasing. The growth of mixedness of reduced state quantified by linear entropy is shown to be related to the degree of initial qubit--environment correlations.
