In this paper, we have proposed a quantum key distribution (QKD) system employing multi-core fiber (MCF). We then theoretically analyze the system performance comprehensively while considering various physical impairments including noise and MCF crosstalk. The feasibility of the proposed architecture is verified via the numerical experiments. The simulation results demonstrate that our developed solution can significantly enhance the secret key rate. It is also shown that the system performanc
