Boundary states for entanglement robustness under dephasing and bit flip channels

引用

Chinese Physics B 2019年第10期28卷 257-262页

作者： hong-mei li Miao-Di Guo Rui Zhang Xue-mei Su College of Physics Jilin University

We investigate the robustness of entanglement for a multiqubit system under dephasing and bit flip channels. We exhibit the difference between the entanglement evolution of the two forms of special states, which are locally unitarily equivalent to each other and therefore possess precisely the same entanglement properties, and demonstrate that the difference increases with the number of qubits n. Moreover, those two forms of states are either the most robust genuine entangled states or the most fragile ones, which confirm that local unitary(LU) operations can greatly enhance the entanglement robustness of n-qubit states.

Lanthanide Thiolate Complexes： Novel Initiators for Ring-opening Polymerization of ε-Caprolactone

引用

Chinese Journal of Chemistry 2005年第11期23卷 1541-1544页

作者： SUN, hong-mei li, Huan-Rong YAO, Chang-Sheng YAO, Ying-Ming SHENG, hong-Ting SHEN, Qi The Key Laboratory of Organic Synthesis of Jiangsu Province College of Chemistry and Chemical Engineering Suzhou University Suzhou 215006 China

The ring-opening polymerization （ROP） of ε-caprolactone （ε-CL） using lanthanide thiolate complexes [（CH3CsH4）2Sm（μ-SPh）（THF）]2 （1） and Sm（SPh）3（HMPA）3 （2） as initiators has been investigated for the first time. Both of 1 and 2 were found to be highly efficient initiators for the ROP of ε-CL. The poly（ε-caprolactone）（PCL） with molecular weight Mn up to 1.97 ×10^5 and relatively narrow molecular weight distributions （1.20〈MW/Mn〈 2.00） have been obtained in high yield in the temperature range of 35-65℃. According to the polymer yield, 2 showed much higher activity than 1. However, the number-average molecular weight of PCL obtained with 2 was much lower than with 1. The possible polymerization mechanism of the ε-CL polymerization has been proposed based on the results of the end group analysis of the ε-CL oligomer.
