两种产品状态的局部克隆

Local cloning of two product states

Zhengfeng Ji, Yuan Feng, Mingsheng Ying

摘要:

局域量子操作和经典通信(LOCC)对克隆和鉴别等量子信息处理任务提出了很大的限制。然而,令人惊讶的是,任何两个纯态的区别在某种意义上都存在这种限制。在本文中,我们表明,克隆是不是那么幸运,即,结论性LOCC克隆的两个产品状态是严格低于全球克隆的效率。

英文摘要:

Local quantum operations and classical communication (LOCC) put considerable constraints on many quantum information processing tasks such as cloning and discrimination. Surprisingly however, discrimination of any two pure states survives such constraints in some sense. In this paper, we show that cloning is not that lucky; namely, conclusive LOCC cloning of two product states is strictly less efficient than global cloning.
