论文摘要
Szilárd发动机是将信息转换为能量的机制（类似于麦克斯韦的恶魔），这似乎违反了热力学的第二定律。最初是经典的思想实验，它扩展到Zurek的量化处理。在这里，我们通过用谐波潜力替换传统的刚性盒，从而扩大了模型的范围，从而研究了量子Szilárd发动机的新型典雅模型。值得注意的是，几乎所有计算都是准确的。本文适用于对信息，熵和量子测量之间的概念联系感兴趣的学生，研究人员和教育工作者。
The Szilárd engine is a mechanism (akin to Maxwell's demon) for converting information into energy, which seemingly violates the second law of thermodynamics. Originally a classical thought experiment, it was extended to a quantized treatment by Zurek. Here, we examine a new, elegant model of a quantum Szilárd engine by replacing the traditional rigid box with a harmonic potential, extending the scope of the model. Remarkably, almost all calculations are exact. This article is suitable to students, researchers and educators interested in the conceptual links between information, entropy, and quantum measurement.
