The Quantum Fourier Transform
The FT has many applications, particularly in the fields of quantum computation and quantum information. In these fields, the FT is often called the quantum Fourier transform. Traditionally, notation used in quantum physics (i.e., the Dirac notation) to denote vectors is different from that used in mathematics. In this chapter, we introduce the Dirac notation and describe the FT in terms of the new notation.
