温度作为量子可观测量

Temperature as a quantum observable

Sushrut Ghonge, Dervis Can Vural

摘要:

在这篇文章中,我们解决了如何观察量子系统的温度的问题。通过提出一个思想实验,我们认为,温度必须被视为一个运营商和它的测量必须伴随着波函数的崩溃。我们建立了一个温度测量装置的模型,并确定了其读数的期望值和量子不确定度。最后,我们探讨了这一观点的后果,并提出了一个实验来验证温度是否确实是一个量子可观测的。

英文摘要:

In this article, we address the problem of how temperature of a quantum system is observed. By proposing a thought experiment, we argue that temperature must be conceived as an operator and its measurement must necessarily accompany a collapse in the wavefunction. We model a temperature measurement device and determine the expectation value and quantum uncertainty of its readout. Lastly, we explore the consequences of this point of view and propose an experiment to verify if temperature is indeed a quantum observable.
