论文简介
Dark-state polaritons in a five-level M-type atomic ensemble are proposed in the electromagnetically induced
transparency. Under conditions of the low excitation limit and adiabatic following, the quantum field can
be mapped onto the atomic polarization states, forming the shape preserving quantum states of polaritons. Two channels for robust quantum memory are provided, which enables the potential applications in quantuminformation
