中文摘要：
通过计算错误量子态与总量子态的比值,引入误态率的概念,分析产生误态的原因,建立量子信令传输损伤模型。通过采用量子中继和全光纤偏振控制器,提出一种量子态均衡策略。分析该策略对损伤模型的影响,对量子态在光纤传输过程中的损耗和色散进行补偿。仿真结果表明,本策略可以降低误态率,增加量子信令传输误态率低于3%阈值时的有效传输距离。
英文摘要：
The error state ratio is introduced by calculating the ratio of the error qubits and total amount of qubits which have been received. The reason of the error state yielded was analyzed to establish a quantum signaling transmission damage model in fiber channel. A quantum state equilibrium strategy was presented by using the quantum repeater technology and all-fiber polarization control scheme. After analyzing the effect of this strategy on damage model, the loss and dispersion of the quantum state during the fiber transmission will be compensated. The simulation results showed that this equilibrium strategy is able to reduce the error state ratio, and increase the quantum signaling effective transmission distance with the error state ratio below the 3% threshold.
