    "abstract": "We propose an efficient quantum key distribution scheme based on\nentanglement. The sender chooses pairs of photons in one of the two equivalent\nnonmaximally entangled states randomly, and sends a sequence of photons from\neach pair to the receiver. They choose from the various bases independently but\nwith substantially different probabilities, thus reducing the fraction of\ndiscarded data, and a significant gain in efficiency is achieved. We then show\nthat such a refined data analysis guarantees the security of our scheme against\na biased eavesdropping strategy.",
