Furthermore we give achievable efficiencies and construct efficient quantum logic network for probabilistic cloning the quantum states used in implemented quantum computation tasks for which cloning provides some enhancement in performance.

• 进而,我们给出了使用概率克隆方法克隆用于贯彻这些量子计算任务的量子态所能达到的最佳系数,并构造了概率克隆一些量子态的有效量子逻辑网。
