In this article, we investigate the unitary dynamics of squashed entanglement and concurrence measures in Werner state and maximally entangled mixed states (MEMS) under two different Hamiltonians. The aim of the present study is twofold. The first part of the study deals with the dynamics under Heisenberg Hamiltonian and the second part deals under bi-linear bi-quadratic Hamiltonian which is the extension of the first Hamiltonian. In both parts, we investigate the dynamical trade-off and equilibrium points for squashed entanglement and concurrence. During the study, we also found the results of entanglement sudden death (ESD) with Heisenberg Hamiltonian in Werner state under concurrence measure. In the second part, we investigate the special result for the bi-linear bi-quadratic Hamiltonian which does not disturb squashed entanglement and concurrence in both the states and exhibits the robust character for both of the states.

在本文中，我们研究了两种不同哈密顿量下维尔纳态和最大纠缠混合态 (MEMS) 中压缩纠缠和并发测度的幺正动力学。本研究的目的是双重的。研究的第一部分处理海森堡哈密顿量下的动力学，第二部分处理双线性双二次哈密顿量下的动力学，这是第一哈密顿量的扩展。在这两部分中，我们研究了压缩纠缠和并发的动态权衡和平衡点。在研究过程中，我们还发现了在并发测度下与维尔纳状态的海森堡哈密顿量发生纠缠猝死（ESD）的结果。在第二部分，
