INVERSE FOURIER TRANSFORM (IFT)
___________________________________________________
E Paramavina.
First apply this IFT.It will show the origin.and again with this apply FT.
you will the have the outcome that is the solution in QUBITS

- Copilot AnswerTo compute the inverse Fourier transform in Python, you can use the following methods:
- numpy.fft.ifft(a, n=None, axis=-1, norm=None, out=None): Computes the one-dimensional inverse discrete Fourier Transform.
- scipy.ifft(y): Computes the inverse fast Fourier transformation for a 1-D numpy array.
- numpy.fft.ifft2(a, s=None, axes=(-2,-1), norm=None, out=None): Computes the 2-dimensional inverse discrete Fourier Transform.
