Abstract
- Unidimensional continuous-variable quantum key distribution (CV-QKD) protocol with Gaussian modulation is simpler in implementation and lower in costs than its two-dimensional counterpart, but its secure transmission distance is not as far as the latter. In this paper, we give a solution that using the photon subtraction, which is one of non-Gaussian operations, to improve the performance of the unidimensional CV-QKD protocol. Security analysis and numerical simulation indicate that the photon subtraction operation can significantly improve the secure transmission distance of the unidimensional CV-QKD protocol.
