论文摘要
在固态系统中研究量子性能是研究的重要途径。在这种情况下，双量子点（DQD）是量子计算和纳米技术中技术突破的多功能平台。这项工作检查了两耦合的DOD中的热纠缠和量子相干性，在该DOD中，该系统暴露于外部刺激中，该刺激会导致每个子系统内的电子过渡。结果表明，外部刺激的引入诱导量子水平交叉，依赖于库仑电位改变了系统的量子纠缠程度和连贯性。因此，可以通过更改过渡频率来调整系统的量子特性，从而增强其量子性能。
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.
