Thermodynamics and Energy


When is Information Erasure Necessary Between Successive Thermodynamic Cycles ?

Authors: François Barriquand

A modified version of Leo Szilard's 1929 thought-experiment is considered, which allows one to show that the iteration of some specially conceived thermodynamic “cycles” does not require any costly memory erasure. These thermodynamic cycles can be easily examined from either a classical or a quantum point of view. Although they differ randomly from each other in certain aspects, their remarkable energy balance remains systematically constant. Similar cycles can prove useful for lowering the theoretical cost of memory erasure in computers.
