It is interesting to note that fundamental properties of the Hadamard operator can be expressed in a neat form, using trigonometric functions of the angle
. Its eigenvectors and eigenvalues are
. A Hadamard gate can be represented in exponential form as
and its square root takes the form
. Here
and
