In 1953, Léon Brillouin derived a general equation stating that the changing of an information bit value requires at least kT ln(2) energy. This is the same energy as the work Leó Szilárd's engine produces in the idealistic case. In his book, he further explored this problem concluding that any cause of this bit value change (measurement, decision about a yes/no question, erasure, display, etc.) will require the same amount of energy.

1953年,布里渊推导出一个一般性方程,证明了改变一个信息的比特值至少需要 kT ln (2)的能量。这与理想情况下 Leó Szilárd 的引擎所产生的能量相同。在他的书中,他进一步探讨了这个问题并得出结论: 任何条件下一个比特的改变(测量、关于是/否问题的决定、擦除、显示等等)都需要消耗相同的能量。
