- Operator Entanglement of Two-Qubit Joint Unitary Operations Revisited: Schmidt Number Approach Hui-Zhi Xia Chao Li Qing Yang Ming Yang Zhuo-Liang Cao Física, Astronomía y Matemáticas Schmidt number Unitary operator Entanglement power Operator entanglement The operator entanglement of two-qubit joint unitary operations is revisited. The Schmidt number, an important attribute of a two-qubit unitary operation, may have connection with the entanglement measure of the unitary operator. We find that the entanglement measure of a two-qubit unitary operators is classified by the Schmidt number of the unitary operators. We also discuss the exact relation between the operator entanglement and the parameters of the unitary operator. 2012 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46423465001 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3-4 Vol.42
