不同类三粒子纠缠态之间的纠缠辅助局域变换

Entanglement-assisted local transformations between inequivalent classes of three-particle entangled states

Iulia Ghiu, Mohamed Bourennane, Anders Karlsson

摘要:

我们证明了二分和三分纠缠态不能作为催化态,使得在局域变换下不可互换的不等价的三粒子纠缠态之间的局域变换成为可能.我们找到了一个最佳的协议转换的某个家庭的W-状态和EPR对到GHz状态。

英文摘要:

We show that bipartite and tripartite entangled states cannot be used as catalysis states to enable local transformations inbetween inequivalent classes of three-particle entangled states which are non-interchangeable under local transformations. We find the optimal protocol for conversion of a certain family of the W-states and an EPR-pair into the GHZ-state.
