论文摘要
自主量子热机不需要外部相干驱动器或工作输入来执行所需的任务，这使它们成为量子系统中热管理的有前途的候选人。在这里，我们提出了一台自动量量子热机器，其中两个未耦合的宏观机械谐振器或微波谐振器通过热热浴中实现了相当大的纠缠。通过将谐振器与共同的两级系统或第三个谐波振荡器耦合并通过热不连贯的热浴中驱动它，从而成为可能。使纠缠的关键步骤涉及通过浴光频谱过滤实现的热水工程。我们的结果表明，浴光谱过滤可以替代典型的非自治储层工程方案来创建异国情调的量子状态。
Autonomous quantum thermal machines do not require an external coherent drive or work input to perform the desired tasks, which makes them a promising candidate for thermal management in quantum systems. Here, we propose an autonomous quantum thermal machine in which two uncoupled macroscopic mechanical resonators or microwave resonators achieve considerable entanglement via a hot thermal bath. This becomes possible by coupling the resonators to a common two-level system or third harmonic oscillator and driving it by the hot incoherent thermal bath. The critical step to make the entanglement involves suitable engineering of the hot bath, realized by bath spectrum filtering. Our results suggest that the bath spectrum filtering can be an alternative to typical non-autonomous reservoir engineering schemes to create exotic quantum states.
