    "abstract": "We propose a distribution scheme of polarization states of a single photon\nover collective-noise channel. By adding one extra photon with a fixed\npolarization, we can protect the state against collective noise via a\nparity-check measurement and post-selection. While the scheme succeeds only\nprobabilistically, it is simpler and more flexible than the schemes utilizing\ndecoherence-free subspace. An application to BB84 protocol through collective\nnoise channel, which is robust to the Trojan horse attack, is also given.",
