Quantum phase estimation and the quantum Fourier transform

Quantum phases can be used to output the results of a quantum algorithm. Now we're going to see a technique for estimating these phases that incorporates another quantum algorithm, in order to ensure that we get a precise estimate. View this video to find out how.
