WebOne is the family of unitary matrices, for which U U † = U †U = I. U U † = U † U = I. This means that the Hermitian conjugate of a unitary is its inverse: another unitary U † U † with the power to undo the effects of U U. All gates in quantum computing, with the exception of measurement and reset operations, can be represented by unitary matrices.
WebSince U is unitary, we can write it as U = e i H for some Hermitian matrix H. But, since U T = U by assumption, this shows that U T = ( e i H) T = e i H T = e i H ¯ = e i H = U, which implies that H is actually real, symmetric. Now, simply define A = e − i H / 2; this matrix is unitary, and with this choice A T U A = I. open the books indianaWebUnitary Matrix.
