  We investigate multipartite quantum correlation (MQC), spatially anisotropic
coupling, and finite temperature effects in a triangular Ising system with
tunable interactions using the exact diagonalization method. We demonstrate
that spatially anisotropic coupling serves as an effective means to modulate
MQC in the antiferromagnetic ground state, which is achievable with current
experimental technologies. Moreover, we explore the interplay between MQC and
spatially anisotropic coupling in the Ising system at finite temperatures. Our
findings reveal a three-way trade-off relationship among high MQC, robust
thermal stability, and anisotropic strength in the triangular Ising system with
antiferromagnetic interactions, though the MQC in the ferromagnetic case is
quite susceptible to temperature changes. These insights contribute to our
understanding of ground state properties and MQC modulation in quantum
many-body systems.
