通过拉曼散射的腔广播

Cavity broadcasting via Raman scattering

Moorad Alexanian

摘要:

广播的概念被扩展到包括的情况下,任意的输入密度状态的双模辐射场产生的输出状态具有相同的边缘状态的各个模式,虽然不同的输入状态。初始未知输入密度态与输出态是幺正相关的,但不等于两个相同的输出边缘态。这种扩展的广播概念提出了一种区分两个非对易量子态的可能方法。

英文摘要:

The notion of broadcasting is extended to include the case where an arbitrary input density state of a two-mode radiation field gives rise to an output state with identical marginal states for the respective modes, albeit different from the input state. The initial unknown input density state is unitarily related to the output state but is not equal to the two identical output marginal states. This extended notion of broadcasting suggests a possible way of discriminating between two noncommuting quantum states.
