    "abstract": "Quantum Fourier transform is of primary importance in many quantum\nalgorithms. In order to eliminate the destructive effects of decoherence\ninduced by couplings between the quantum system and its environment, we propose\na robust scheme for quantum Fourier transform over the intrinsic\ndecoherence-free subspaces. The scheme is then applied to the circuit design of\nquantum Fourier transform over quantum networks under collective decoherence.\nThe encoding efficiency and possible improvements are also discussed.",
