| Abstract: | The influence of the disturbance caused by the imperfection of the engineering coupling constantsin the perfect state transfer is calculated. The results show thatthe fidelity for the perfect state transfer is seriously affectedby the errors occurring near the input and output spins. Suchresults are helpful for the realization of the perfect statetransfer in the case where there exist errors in experiments. |
