在一个反事实的量子密钥分配方案中，仅仅通过传输单个粒子的分裂真空脉冲就可以产生秘密密钥。基于反事实现象，改进了第一种量子密钥分配方案的效率。该方案不仅达到了与原方案相同的安全级别，而且具有更高的效率。并分析了在不同条件下如何达到最优效率。
In a counterfactual quantum key distribution scheme, a secret key can be generated merely by transmitting the split vacuum pulses of single particles. We improve the efficiency of the first quantum key distribution scheme based on the counterfactual phenomenon. This scheme not only achieves the same security level as the original one but also has higher efficiency. We also analyze how to achieve the optimal efficiency under various conditions.
