| Abstract: | We give a brief review on the quantum information processing in decoherence-free subspace (DFS). We show how to realize the
initialization of the entangled quantum states, information transfer and teleportation of quantum states, two-qubit Grover
search and how to construct the quantum network in DFS, within the cavity QED regime based on a cavity-assisted interaction
by single-photon pulses.
