论文摘要
探索了通过探索由热储层终止的谐振器之间的可调节的旋转量子置量的通用超导设置的量子传热。考虑了两种类型的体系结构，即顺序和梁分离器设置。应用数值精确的运动层次方程（HEOM）方法，揭示了稳态特性，并确定了与实验相关的参数集。将基准结果与基于近似处理的预测进行比较，以证明其在参数空间的宽范围内的失败。这些发现可能允许改善超导设备中热控制的未来设计。
Quantum heat transfer through a generic superconducting set-up consisting of a tunable transmon qubit placed between resonators that are termined by thermal reservoirs is explored. Two types of architectures are considered, a sequential and a beam splitter setting. Applying the numerical exact hierarchical equation of motion (HEOM) approach, steady state properties are revealed, and experimentally relevant parameter sets are identified. Benchmark results are compared with predictions based on approximate treatments to demonstrate their failure in broad ranges of parameter space. These findings may allow to improve future designs for heat control in superconducting devices.
