In this paper, we consider a special type of maximally entangled states namely by entangled SU(1,1) semi coherent states by using SU(1,1) semi coherent states(SU(1,1) Semi CS). The entanglement characteristics of these entangled states are studied by evaluating the concurrence.We investigate some of their nonclassical properties,especially probability distribution function,second-order correlation function and quadrature squeezing . Further, the quasiprobability distribution functions (Q-functions) is discussed.

最大纠缠SU（1,1）半相干态

在本文中，我们考虑一种特殊的最大纠缠态，即通过使用SU（1,1）半相干态（SU（1,1）Semi CS）纠缠SU（1,1）半相干态。通过评估它们的并发性来研究这些纠缠态的纠缠特性。我们研究了它们的一些非经典性质，特别是概率分布函数，二阶相关函数和正交压缩。此外，讨论了拟概率分布函数（Q函数）。
