    "abstract": "We propose easy implementable protocols for robust quantum key distribution\nwith the collective dephasing channel or collective rotating channel.\n  In these protocols, Bob only takes passive photon detection to measure the\npolarization qubits in the random bases. The source for the protocol with\ncollective rotating channel is made by type 2 spontaneous parametric down\nconversion with random unitary rotation and phase shifter, no quantum\ndisentangler is required.\n  A simple proof for unconditionally security is shown.",
