Abstract
The channel estimation is one of the essential components to make the long distance transmission of continuous variable quantum key distribution (CV-QKD). In this paper we provide the Cramer-Rao lower bound (CRLB) of the channel estimator, which is the minimum variance that an estimator can achieve. We compare CRLB with the channel transmission parameter estimator proposed in [15] for long distance CV-QKD systems.
