Landauer原理的推广

Generalising Landauer's Principle

O. J. E. Maroney

摘要:

在最近的一篇论文[Mar05]中,有人认为,要正确理解朗道原理的热力学,有必要扩展逻辑运算的概念,使其包括不确定性运算。在这里,我们更详细地研究这种操作的热力学,扩展Landuaer[Lan61]的工作,包括不确定性操作,并包括可变熵,温度和平均能量的逻辑状态。我们导出了Landauer原理的最一般的表述,并证明了它的普适性,大大扩展了以前证明的有效性。这证实了[Mar05b]中所做的说明,特别是所有逻辑运算原则上都可以以可逆的方式进行。我们展示了一个物理过程,可以执行任何计算,而无需工作要求或与环境进行热交换。朗道原理的许多广泛的陈述被证明只是我们的一般原理的特殊情况。

英文摘要:

In a recent paper [Mar05] it is argued that to properly understand the thermodynamics of Landauer's Principle it is necessary extend the concept of logical operations to include indeterministic operations. Here we examine the thermodynamics of such operations in more detail, extending the work of Landuaer[Lan61] to include indeterministic operations and to include logical states with variable entropies, temperatures and mean energies. We derive the most general statement of Landauer's Principle and prove it's universality, extending considerably the validity of previous proofs. This confirms conjectures made in [Mar05b], in particular that all logical operations may, in principle, be performed in a thermodynamically reversible fashion. We demonstrate a physical process that can perform any computation without work requirements or heat exchange with the environment. Many widespread statements of Landauer's Principle are shown to be only special cases of our generalised principle.
