Abstract
Based on a cavity-assisted single-photon input–output process, we first construct the hybrid controlled-phase-flip gate between photon and the single-logic qubit in decoherence-free subspaces. And we also achieve the universal single-qubit logic operations. We realize the distributed quantum information processing with the hybrid controlled-phase-flip gate and single-qubit logic operations. Finally, we discuss the experimental feasibility of our scheme, which is satisfied with currently available technology.
