Xihan Li, Xiao-jiao Duan · 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 a quantum state is encoded in a frequency state during the transmission and transferred to a polarization state later. Both the fidelity of the quantum state transmitted and the success probability of this scheme are 100% in principle.
