    "abstract": "We propose an easy implementable prepare-and-measure protocol for robust\nquantum key distribution with photon polarization. The protocol is fault\ntolerant against collective random unitary channel noise. The protocol does not\nneed any collective quantum measurement or quantum memory. A security proof and\na specific linear optical realization using spontaneous parametric down\nconversion are given.",
