    In this paper, a proposal for how to store and retrieve the quantum state of a nonstationary photon wave packet in quantum dots is presented. Here, the input photon with two central frequencies is different from the usual photon. In order to store the quantum state of the input photon more stably, we control the magnetic field to transfer the coherence from electronic spins to nuclear spins. In this paper, we also suggest one method to produce a photon with two central frequencies, and point out a possible way to code quantum information.
