    "abstract": "We report the experimental demonstration of a transmission scheme of photonic\nqubits over unstabilized optical fibers, which has the plug-and-play feature as\nwell as the ability to transmit any state of a qubit, regardless of whether it\nis known, unknown, or entangled to other systems. A high fidelity to the\nnoiseless quantum channel was achieved by adding an ancilla photon after the\nsignal photon within the correlation time of the fiber noise and by performing\nquantum parity checking. Simplicity, maintenance-free feature and robustness\nagainst path-length mismatches among the nodes make our scheme suitable for\nmulti-user quantum communication networks.",
