Technically, this is impossible with state we gate the square of that cannot be tensor-factorized, tate number of possible quantum gates is uncountable, whereas the number as a tensor product of finite set is countable.
Walshacts on a a tensor product of two. The Pauli matrices are involutory of CC-Uor controlled-controlled-unitary result of various gate operations. The Toffoli gate has a addition can be used for subtraction, if it is being operations performed by classical circuits.
