Classic logic gates are not reversible in the sense that after a logical operation, it is not possible to reconstitute the input states of the recorded output. For this reason, it is considered that the classical computation process is one with increasing entropy (loss of information), which, together with well-known classical physical thermodynamics, will introduce a new field of study, referring to the so-called information thermodynamics.
