    "abstract": "We examine in detail the quantum memory technique for photons in a double\n$\\Lambda$ atomic ensemble in this work. The novel application of the present\ntechnique to create two different quantum probe fields as well as entangled\nstates of them is proposed. A larger zero-degeneracy class besides dark-state\nsubspace is investigated and the adiabatic condition is confirmed in the\npresent model. We extend the single-mode quantum memory technique to the case\nwith multi-mode probe fields, and reveal the exact pulse matching phenomenon\nbetween two quantized pulses in the present system.",
