    "abstract": "We present an experimental demonstration of a quantum key distribution\nprotocol using coherent polarization states. Post selection is used to ensure a\nlow error rate and security against beam splitting attacks even in the presence\nof high losses. Signal encoding and readout in polarization bases avoids the\ndifficult task of sending a local oscillator with the quantum channel. This\nmakes our setup robust and easy to implement. A shared key was established for\nlosses up to 64%.",
