  This article explores the concurrence, including entanglement, in a two-qubit
Heisenberg XXX chain with Dzyaloshinskii-Moriya and
Kaplan-Shekhtman-Entin-Wohlman-Aharony interactions. The concurrence expression
was developed using the physical variables connected with the chosen system.
Our results indicate that temperature, the spin coupling constant $J$, the
x-components $D_x$, and $\Gamma_x$ may all play a role in determining the
degree of intricacy between states. Additionally, these findings imply that the
separability of states is possible for high-temperature domains or
ferromagnetic chains. In contrast, the entanglement of states may be achieved
by using high values for the x-components $D_x$ or $\Gamma_x$ parameters or by
using an antiferromagnetic chain.
