  Landauer referred to this operation as resetting, although in much of the succeeding literature this has become known as erasure. This has caused some confusion as “erasing” information could be taken just to mean an operation which destroys the original information, without necessarily leaving the system determinately in the zero state. An example of such ‘erasure-by-destruction’ would be to simply remove the partition from the box, wait long enough for thermalisation to randomise the location of the molecule, then reinsert the partition in the centre of the box.  Such an operation would clearly destroy the original information, represented by the original location of the molecule, but requires no work to be performed. However, it is also clearly not an implementation of the reset operation.
