Quantum Fourier Transform (QFT) is a linear transformation on quantum bits and is the quantum analogue of the discrete Fourier transform. The quantum Fourier transform is a part of many quantum algorithms, notably Shor's algorithm for factoring and computing the discrete logarithm, the quantum phase estimation algorithm for estimating the eigenvalues of a unitary operator, and algorithms for the hidden subgroup problem.

Estimating $\pi$ using Quantum Computing - why does it work only in simulator?
Actual Quantum Hardware is very noisy, hence you can't get the desired result, running your code directly onto it. What you can do instead is make use of some error mitigation techniques.
