朗道原理指出，信息的擦除必须是一个耗散过程。在本文中，我们仔细分析了物理存储器上信息的记录和擦除。一方面，我们表明，为了记录一些信息，记忆必须被赶出平衡。另一方面，我们推导出朗道原理的微分版本：我们将每次擦除过程中产生熵的速率与信息被擦除的速率联系起来。版权所有（C）2013 EPLA
Landauer's principle states that the erasure of information must be a dissipative process. In this paper, we carefully analyze the recording and erasure of information on a physical memory. On the one hand, we show that, in order to record some information, the memory has to be driven out of equilibrium. On the other hand, we derive a differential version of Landauer's principle: We link the rate at which entropy is produced at every time of the erasure process to the rate at which information is erased.
