Abstract
Lindblad-type equation is used to describe flux qubit evolution. In the frame of informational approach two types of flux qubit - three-junction qubit based on low-inductive π -interferometer and two-junction qubit based on low-inductive φ-interferometer - are considered and compared. Such approach to flux qubit analysis can be used to study the coherence state decay in the measurement procedure.
