Continuous-variable quantum key distribution (QKD) utilizes an ensemble of coherent states of light to distribute secret encryption keys between two parties in the presence of an eavesdropper (Left). The effect of reconciliation efficiency on the asymptotic secure key rate between distant parties. We proposed some MET-LDPC codes with low FER and high efficiency $\beta$ to obtain a maximum possible secure key rate (Right)
