经典关联的量子和经典混合生成

Quantum and Classical Hybrid Generations for Classical Correlations

Xiaodie Lin, Zhaohui Wei, Penghui Yao

摘要:

我们考虑两阶段的混合协议,结合量子资源和经典资源,以产生两个独立的参与者共享的经典相关。我们的动机是双重的。首先,在不久的将来,量子信息处理的规模是相当有限的,当可用的量子资源不足以完成某些任务时,一种可能的方法来增强量子方案的能力是引入额外的经典资源。我们分析了这些混合协议的数学结构,并描述了量子资源和经典资源之间的关系。其次,通信复杂性理论中的一个基本的开放问题是描述共享先验量子纠缠相对于共享先验随机性的优势,这仍然是广泛开放的。事实证明,我们的量子和经典的混合协议提供了新的见解,这个重要的问题。

英文摘要:

We consider two-stage hybrid protocols that combine quantum resource and classical resource to generate classical correlations shared by two separated players. Our motivation is twofold. First, in the near future the scale of quantum information processing is quite limited, and when quantum resource available is not sufficient for certain tasks, a possible way to strengthen the capability of quantum schemes is introducing extra classical resource. We analyze the mathematical structures of these hybrid protocols, and characterize the relation between the amount of quantum resource and classical resource needed. Second, a fundamental open problem in communication complexity theory is to describe the advantages of sharing prior quantum entanglement over sharing prior randomness, which is still widely open. It turns out that our quantum and classical hybrid protocols provide new insight into this important problem.
