| dc.description | For a flux qubit described by a two-level system of equations we propose a special time dependent external control field. We show that for a qubit placed in this field there exists a critical value of tunnel frequency. When the tunnel frequency is close to its critical value, the probability value of a definite direction of the current circulating in a Josephson-junction circuit may be kept above 1/2 during a desirable time interval. We also show that such a behavior is not much affected by a sufficiently small dissipation. | |
