局域克隆非极大W态的纠缠和混合

Entanglement and Mixed ness of Locally Cloned Non - Maximal W - State

Indranil Chakrabarty, Sovik Roy, Nirman Ganguly, Binayak S. Choudhury

摘要:

本文描述了一个协议,通过该协议,三方中的两方在不涉及第三方的情况下,从三个远距离伙伴共享的非最大W态或W型态$|X>=α|001>_{123}+β|010>_{123}+γ|100>_{123}, α^{2} + β^{2} + γ^{2} = 1$生成两个二体纠缠态。我们还考虑了$β=γ$的情形,得到了局部输出态可分而非局部输出态不可分的$α^2$的一个值域.我们还发现了不可分态的混合性与它们的不可分量的依赖关系,对于该范围的$α^2$。

英文摘要:

In this work we describe a protocol by which two of three parties generate two bipartite entangled state among themselves without involving third party, from a non maximal W state or W - type state $|X>=α|001>_{123}+β|010>_{123}+γ|100>_{123}, α^{2} + β^{2} + γ^{2} = 1$ shared by three distant partners. Also we have considered the case $β=γ$, to obtain a range for $α^2$, for which the local output states are separable and non local output states are inseparable. We also find out the dependence of the mixed ness of inseparable states with their amount of inseparability, for that range of $α^2$.
