论文摘要
在具有预言量子优势的新兴技术中，量子通信已经导致了引人入胜的示范 - 包括量子传送到卫星和卫星。但是，所有光学通信都需要使用光学设备，并且它们的全面量子热力学描述仍然严重缺乏。在目前的分析中，我们证明了Landauer原理的嘈杂极化器的原理，即吸收线性极化器和偏光梁插图器。作为主要结果，我们获得了第二定律的陈述，这些法律量化了在线性极化光的创建中消散的最小热量。我们的发现以实验性易处理的例子为例，即量子橡皮擦的温度依赖性。
Among the emerging technologies with prophesied quantum advantage, quantum communications has already led to fascinating demonstrations -- including quantum teleportation to and from satellites. However, all optical communication necessitates the use of optical devices, and their comprehensive quantum thermodynamic description is still severely lacking. In the present analysis we prove several versions of Landauer's principle for noisy polarizers, namely absorbing linear polarizers and polarizing beamsplitters. As main results we obtain statements of the second law quantifying the minimal amount of heat that is dissipated in the creating of linearly polarized light. Our findings are illustrated with an experimentally tractable example, namely the temperature dependence of a quantum eraser.
