论文摘要
在量子热力学和量子信息科学中，热机和量子相关之间的相互作用引起了极大的兴趣。最近，已经提出了量子szilárd发动机，表明麦克斯韦的恶魔和工作媒介之间的量子可识别性可能对工作提取任务有益。然而，这种类型的量子燃料机通常在存在腐蚀作用的情况下脆弱。我们提供了一个纯dephasing过程的示例，表明发动机的量子性可以降解。因此，在这项工作中，我们通过引入一个可以访问控制系统并使工作媒介以量子叠加的方式通过两个dephasing渠道的第二个恶魔来解决这个问题。此外，我们提供了一个量子电路来模拟我们提出的概念并在IBMQ和IONQ量子计算机上进行测试。
The interplay between thermal machines and quantum correlations is of great interest in both quantum thermodynamics and quantum information science. Recently, a quantum Szilárd engine has been proposed, showing that the quantum steerability between a Maxwell's demon and a work medium can be beneficial to a work extraction task. Nevertheless, this type of quantum-fueled machine is usually fragile in the presence of decoherence effects. We provide an example of the pure dephasing process, showing that the engine's quantumness can be degraded. Therefore, in this work, we tackle this question by introducing a second demon who can access a control system and make the work medium pass through two dephasing channels in a manner of quantum superposition. Furthermore, we provide a quantum circuit to simulate our proposed concept and test it on IBMQ and IonQ quantum computers.
