Due to the [[Unitarity (physics)|unitarity]] of [[quantum mechanics]], [[quantum circuit]]s are reversible, as long as they do not "[[wave function collapse|collapse]]" the [[quantum state]]s on which they operate.<ref name="Williams">{{cite book |author=Williams |first=Colin P. |title=Explorations in Quantum Computing |publisher=[[Springer Science+Business Media|Springer]] |year=2011 |isbn=978-1-84628-887-6 |pages=25–29}}</ref>

±==Reversibility<!--'Logical reversibility', 'Charge recovery logic', and 'Adiabatic computing' redirect here-->==

There are two major, closely related types of reversibility that are of particular interest for this purpose: [[Reversible process (thermodynamics)|physical reversibility]] and '''logical reversibility'''<!--boldface per WP:R#PLA-->.<ref>{{Cite web | url=http://www.cise.ufl.edu/research/revcomp/ |title = The Reversible and Quantum Computing Group (Revcomp)}}</ref>
