Quantum fourier transform inverse
Websingle unitary transformation: the quantum Fourier transform. This is a discrete Fourier transform, not upon the data stored in the system state, but upon the state itself. Let’s look at the definition to make this a bit clearer. The discrete Fourier transform (DFT) f˜of a discrete function f1,...,fN and its inverse are given by f˜ k ≡ 1 ... WebSep 10, 2015 · 8. I am trying to prove that the inverse of the fourier transform is equal to its adjoint (i.e. it is a unitary linear operator). I am working with the inner product . The Fourier transform (and inverse (I do not require the proof of the inverse)) is as follows: I know the adjoint is defined such that . It is from here, however, that I am ...
