Long-distance high-fidelity continuous-variable quantum key distribution with non-Gaussian operations: An exact closed form solution

Khatereh Jafari, Mojtaba Golshani, Alireza Bahrampour

In this paper, we derive a closed form expression for the output state of a CV-QKD protocol in the presence of zero-photon catalysis (ZPC) and quantum scissor (QS). Then, based on…
