  Studying quantum properties in solid-state systems is a significant avenue
for research. In this scenario, double quantum dots (DQDs) appear as a
versatile platform for technological breakthroughs in quantum computation and
nanotechnology. This work inspects the thermal entanglement and quantum
coherence in two-coupled DODs, where the system is exposed to an external
stimulus that induces an electronic transition within each subsystem. The
results show that the introduction of external stimulus induces a quantum level
crossing that relies upon the Coulomb potential changing the degree of quantum
entanglement and coherence of the system. Thus, the quantum properties of the
system can be tuned by changing the transition frequency, leading to the
enhancement of its quantum properties.
