最近李等。当在量的量隧道控制了远距传物，建议了特殊部分纠缠的状态服务，当在他们的计划有一些限制时。基于那，我们在场在这份报纸的可能的改进。我们构造对完美的控制远距传物合适的一个新奇三粒子的部分纠缠的状态。一个简单的量电路被设计获得这个状态。我们评估量从三个观点的控制远距传物：远距传物忠实，成功概率和控制器是力量。详细计算和模拟分析证明构造状态是为任意的 qubits 的控制远距传物的一条合适的隧道，统一远距传物忠实和 100% 成功概率能被完成。同时，只要隧道是，纠纷度等于到或比 3/4 大，控制器的力量能被保证。

英文摘要：

Recently Li et al. proposed special partially entangled states serving as quantum channel in quantum controlled teleportation, while there are some limitations in their scheme. Based on that, we present a possible improvement in this paper. We construct a novel three-particle partially entangled state which is suitable for perfect controlled teleportation. A simple quantum circuit is designed to obtain this state. We evaluate quantum controlled teleportation from three points of view： teleportation fidelity, success probability and the controller＇s power. Detailed calculations and simulation analyses show that the constructed state is a suitable channel for controlled teleportation of arbitrary qubits, unit teleportation fidelity and 100% success probability can be achieved. Meanwhile, as long as channel＇s entanglement degree equals to or greater than 3/4, the controller＇s power can be guaranteed.
