原文:
Landauer’s principle gives a lower bound on the amount of energy it takes to erase one bit of information: E ≥ log(2) kB T where kB is the Boltzmann constant and T is the ambient temperature in Kelvin. The lower bound applies no matter how the bit is physically stored. There is no theoretical lower limit on the energy required to carry out a reversible calculation. In practice the energy required to erase a bit is around a billion times greater than Landauer’s lower bound. You might reasonabl…
译文:
Landauer原理给出了擦除一位信息所需能量的下限： E ≥ log (2) kB T ，其中kB是玻尔兹曼常数， T是以开尔文为单位的环境温度。无论位如何物理存储，下限都适用。进行可逆计算所需的能量没有理论上的下限。在实践中，擦除位所需的能量大约是 han Landauer的下限。你可能会讲道理……
