Homework Statement
Show that |A_ij| ≤ 1 for every entry A_ij of a Unitary Matrix A.
Homework Equations
A matrix is unitary when A^†*A=I
Where † is the hermitian operator, meaning you Transpose and take the complex conjugate
and I = the identity matrix
The Attempt at a Solution
I'm having a hard time starting this one out.
It seems to make sense to me, as we need to find a way to make them equal the identity matrix.
So we have something like:
[Aij*T][Aij]
[Aji*][Aij]
I'm not quite sure where to go in any direction, how I can get the necessary conditions applied to this proof.
Any point of guidance may help.
