一类量子态的形成纠缠

Entanglement of Formation for a Class of Quantum States

Shao-Ming Fei, Juergen Jost, Xianqing Li-Jost, Guo-Fang Wang

摘要:

利用$N$维量子系统的广义纠缠公式,研究了一类高维量子混合态的纠缠形成。作为应用,计算了一类$16\times 16$密度矩阵的形成纠缠。

英文摘要:

Entanglement of formation for a class of higher dimensional quantum mixed states is studied in terms of a generalized formula of concurrence for $N$-dimensional quantum systems. As applications, the entanglement of formation for a class of $16\times 16$ density matrices are calculated.
