We experimentally demonstrate a proposal [Phys. Rev. A 87, 052325 (2013)] ofa scheme for robust distribution of polarization entangled photon pairs overcollective noisy channels having the reciprocity. Although the scheme employsthe robustness of two qubit decoherence-free subspace, by utilizing the forwardpropagation of one half of the entangled photons and the backward propagationof a classical reference light, it achieves an entanglement-sharing rateproportional to the transmittance of the quantum channel for the signal photon.We experimentally observed the efficient sharing rate while keeping a highlyentangled state after the transmission. We also show that the protection methodis applicable to transmission of arbitrary polarization state of a singlephoton.
