Reconciliation is an essential procedure for continuous-variable quantum key distribution (CV-QKD). As the most commonly used reconciliation protocol in short-distance CV-QKD, the slice error correction (SEC) allows a system to distill more than 1 bit from each pulse. However, its quantization efficiency is greatly affected by the noisy channel with a low signal-to-noise ratio (SNR), which usually limits the secure distance to about 30 km. In this paper, an improved SEC protocol, named Rotation… Expand

Novel Reconciliation Protocol Based on Spinal Code for Continuous-variable Quantum Key Distribution
A novel rateless reconciliation protocol based on spinal code is proposed, which can achieve a high-efficiency and adaptive reconciliation in a larger range of SNRs and is suitable for hardware implementation, thus it also has the potential of high-speed hardware implementation. Expand
Efficient rate-adaptive reconciliation for continuous-variable quantum key distribution
This protocol changes the code rate of multi-edge type low density parity check codes, by puncturing and shortening techniques, to enlarge the correctable signal-to-noise ratios regime, thus improves the overall reconciliation efficiency comparing to the original fixed rate reconciliation protocol.

Overcoming the rate–distance limit of quantum key distribution without quantum repeaters
This work introduces an alternative scheme for QKD whereby pairs of phase-randomized optical fields are first generated at two distant locations and then combined at a central measuring station, enabling a form of quantum key distribution that can exceed the secret-key capacity without using quantum repeaters and that has security independent of the measuring devices.

Quasi-cyclic multi-edge LDPC codes for long-distance quantum cryptography
A high-throughput error correction scheme is developed that increases the potential operating range for quantum key distribution from 100 to 143 km and is fast enough that the rate of key distribution is instead limited by the physical properties of the communication channel. Expand
