# Phase Estimation Algorithm¶

## Overview¶

The phase estimation algorithm is a quantum subroutine useful for finding the eigenvalue corresponding to an eigenvector $$u$$ of some unitary operator. It is the starting point for many other algorithms and relies on the inverse quantum Fourier transform. More details can be found in references [1].
