Efficient polarization qubit transmission assisted by frequency degree of freedom [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2011 We present an efficient arbitrary polarization qubit transmission scheme against channel noise by utilizing frequency degree of freedom, which is more stable in transmission surroundings. The information of quantum state is encoded in frequency state during the transmission and transferred to polarization state later. Both the fidelity of quantum state
