摘要

In this paper we study the influence of the Dzyaloshinskii-Moriya (DM) interaction on the (swap)^α operation of spin qubits in two coupled quantum dots. It is shown that a sequence of single-qubit rotations as well as properly chosen width and strength of the exchange coupling pulse are effective to correct the error caused by the DM term. Depending on the amplitude of the DM interaction, the operation error is either fully or partly correctable.
