We describe the method to determine an orthonormalized basis of Josephson quantum bit states under two-level approximation for the case when the system`s potential is a set of two potential wells, separated by tunnel barrier. This basis is useful for calculation of qubit`s Hamiltonian matrix. The calculations were carried out both for well-known three-junction and four-junction flux qubits and for perspective silent qubits.
