Abstract How to implement multi-qubit gates is an important problem in quantum information processing. Based on cross phase modulation, we present approach realizing a family of that deterministically operate single photons as the qubits. A general n -qubit unitary operation typical example these gates. The greatly relax requirement resources, such ancilla and coherent beams, well number operations improvement this framework may facilitate large scale
