phase estimation

The story of quantum phase estimation starts with a unitary matrix \(U\). Suppose \(|x\rangle\) is an eigenvector of \(U\) so that \(U|x\rangle=\lambda|x\rangle\) for some…

QFT

The Fourier transform is a beautiful function with many important applications. There is a wonderful introduction to the Fourier transform by 3 Blue 1 Brown that is well worth watching. The following is a description of the quantum Fourier transform (QFT). After defining a closed formula for QFT, I will explain how to build the…
