Abstract

A scheme for implementing discrete quantum Fourier transform is
proposed via quantum dots embedded in a microcavity, and then some
of its applications are investigated, i.e., Deutsch-Jozsa algorithm and Shor's quantum factoring. In particular, the detailed process of implementing one-qubit Deutsch-Jozsa algorithm and the factorization of N=15 are given. The microcavity mode is only virtually excited in the whole interaction, so the effective decoherent has slight effect on the current scheme. These schemes
would be an important step to fabricate a solid quantum computer.
