论文摘要
在开放的量子系统中，工作和热量之间的明确区别通常是具有挑战性的，将量子jarzynski相等扩展到超出一般量子通道下在一般量子通道下进化的系统仍然是量子热力学的开放问题。在这封信中，我们通过利用一次性测量方案来介绍定义明确的猜测量子热和猜测量子工作的概念，该方案仅需要对系统进行初始的能量测量。我们得出了一个修改的量子jarzynski平等，以及相对于猜测的量子工作的最大工作原理，这仅需要系统的知识。我们通过将量子热量与量子假设检验的问题联系起来，进一步显示了猜测量子热量的重要性。
In open quantum systems, a clear distinction between work and heat is often challenging, and extending the quantum Jarzynski equality to systems evolving under general quantum channels beyond unitality remains an open problem in quantum thermodynamics. In this Letter, we introduce well-defined notions of guessed quantum heat and guessed quantum work, by exploiting the one-time measurement scheme, which only requires an initial energy measurement on the system alone. We derive a modified quantum Jarzynski equality and the principle of maximum work with respect to the guessed quantum work, which requires the knowledge of the system only. We further show the significance of guessed quantum heat and work by linking them to the problem of quantum hypothesis testing.
