Abstract
By analogy with the number-difference-phase theory in quantum optics, we in troduce nonlinear Bose operator to represent the phase across Josephson jun ction, and build a bosonic operator Josephson qubit model, which establish itself firmly on the ground of charge state representation and phase state representation. The operator version of Josephson equations are also obtain ed. (C) 2001 Elsevier Science B.V. All rights reserved.
