热力学可逆性和逻辑可逆性之间的关系(缺乏)

The (absence of a) relationship between thermodynamic and logical reversibility

O. J. E. Maroney

摘要:

Landauer擦除似乎在热力学和信息处理(逻辑计算)之间提供了强有力的联系。唯一需要产生热量的逻辑操作是逻辑上不可逆的操作,最小的热量产生是每丢失一位信息产生$kT \ln 2$。然而,它将显示逻辑可逆性既不意味着,也不意味着热力学可逆性。通过研究逻辑上不可逆的物理可逆运算,可以表明信息和熵虽然具有相同的形式,但在概念上是不同的。

英文摘要:

Landauer erasure seems to provide a powerful link between thermodynamics and information processing (logical computation). The only logical operations that require a generation of heat are logically irreversible ones, with the minimum heat generation being $kT \ln 2$ per bit of information lost. Nevertheless, it will be shown logical reversibility neither implies, nor is implied by thermodynamic reversibility. By examining thermodynamically reversible operations which are logically irreversible, it is possible to show that information and entropy, while having the same form, are conceptually different.
