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

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

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 a quantum scissor (QS). Then, based on this closed-form solution, we use a direct search algorithm to find the appropriate values of input state and QS param...
