Discrete quantum Fourier transform in coupled semiconductor double quantum dot molecules
arXiv:0704.2091 · doi:10.1016/j.physleta.2008.11.005
Abstract
In this Letter, we present a physical scheme for implementing the discrete quantum Fourier transform in a coupled semiconductor double quantum dot system. The main controlled-R gate operation can be decomposed into many simple and feasible unitary transformations. The current scheme would be a useful step towards the realization of complex quantum algorithms in the quantum dot system.
