摘要: 超算符是指将算子映射为算子的线性映射,任意一个超算符既有自然表示又有Choi-Jamiolkowski表示,这两种表示仅仅与超算符本身有关.该文首先讨论了超算符φ∈BB(X))的自然表示Nφ和Choi-Jamiolkowski表示Jφ,然后给出了他们之间的相互转换关系:Nφ=TJφ),并列举了几个重要的例子.

关键词: 超算符, 表示, 转换, 量子运算

Abstract: Super operator is the linear mapping which performs the operator to operator, any super operator has the natural representation and Choi-Jamiolkowski representation, both of them are only dependent on the super-operator itself. In this paper, the natural representation Nφ and Choi-Jamiolkowski representation Jφ of a given super operator φ∈B(B(X)) is discussed, and then the transform relationship between them is established as Nφ=T (Jφ), then some important examples are presented.

Key words: Super operators, Representation, Transformation, Quantum operation
