有效温度下Landauer复位的产热与误差概率关系

Heat production and error probability relation in Landauer reset at effective temperature

Igor Neri, Miquel López-Suárez

摘要:

一个经典信息位的擦除是一个耗散过程。1961年,Rolf Landauer从理论上推导出该操作期间产生的最小热量等于$k_B T \ln 2$,并命名为Landauer极限、Landauer重置或Landauer原理。尽管兰道极限具有根本的重要性,但它在50多年的时间里一直没有得到实验验证,直到最近才用胶体粒子和磁点进行了测试。对不同设备的实验测量,如微机械系统或纳米电子设备仍然缺失。在这里,我们展示了在一个微机械系统中进行Landauer复位操作,在一个有效的温度下操作所获得的结果。测得的热交换符合理论,达到接近预期极限的值。然后将获得的热产生数据与完成复位操作的错误概率相关联。

英文摘要:

The erasure of a classical bit of information is a dissipative process. The minimum heat produced during this operation has been theorized by Rolf Landauer in 1961 to be equal to $k_B T \ln 2$ and takes the name of Landauer limit, Landauer reset or Landauer principle. Despite its fundamental importance, the Landauer limit remained untested experimentally for more than fifty years until recently when it has been tested using colloidal particles and magnetic dots. Experimental measurements on different devices, like micro-mechanical systems or nano-electronic devices are still missing. Here we show the results obtained in performing the Landauer reset operation in a micro-mechanical system, operated at an effective temperature. The measured heat exchange is in accordance with the theory reaching values close to the expected limit. The data obtained for the heat production is then correlated to the probability of error in accomplishing the reset operation.
