摘要：
In this paper, we discuss the coherence for duality quantum computers under taking different unitary operators acting on pure states. Firstly, for arbitrary unitary operators, we give some general quantitative results of the coherence of output states. Secondly, for incoherence unitary operators, we obtain that the coherence of output states satisfies an inequality. In addition, we also give a conclusion of the coherence of output states under unitary permutation operators.
