二体量子态形成的纠缠

Entanglement of Formation of Bipartite Quantum States

Kai Chen, Sergio Albeverio, Shao-Ming Fei

摘要:

通过构造一个函数的凸壳,给出了任意两体混合态形成纠缠的严格下界。这是通过揭示形成的纠缠,著名的Peres-Horodecki和重新排列的标准之间的新的连接。该界给出了一种十分简单有效的计算方法来定量地计算任意两体量子态的纠缠度。

英文摘要:

We give an explicit tight lower bound for the entanglement of formation for arbitrary bipartite mixed states by using the convex hull construction of a certain function. This is achieved by revealing a novel connection among the entanglement of formation, the well-known Peres-Horodecki and realignment criteria. The bound gives a quite simple and efficiently computable way to evaluate quantitatively the degree of entanglement for any bipartite quantum state.
