Equation 11 in our paper is not correct. It has been pointed out that the secure key generation rate is reduced even in the case QBER =0 1. Lower bounds for the secure key generation rate as a function of detector efficiency mismatch and QBER have been proved in Refs. 2,3. For the case treated in our article the rate satisfies
