Information Reconciliation for Continuous-Variable Quantum Key Distribution using Non-Binary Low-Density Parity-Check Codes
نویسندگان
چکیده
An information reconciliation method for continuous-variable quantum key distribution with Gaussian modulation that is based on non-binary low-density paritycheck (LDPC) codes is presented. Sets of regular and irregular LDPC codes with different code rates over the Galois fields GF(8), GF(16), GF(32), and GF(64) have been constructed. We have performed simulations to analyze the efficiency and the frame error rate using the sum-product algorithm. The proposed method achieves an efficiency between 0.94 and 0.98 if the signal-to-noise ratio is between 4 dB and 24 dB. keywords: continuous variable quantum key distribution postprocessing, information reconciliation, non-binary low-density parity-check codes ∗[email protected]

Efficient Reconciliation of Correlated Continuous Random Variables using LDPC Codes
This paper investigates an efficient and practical information reconciliation method in the case where two parties have access to correlated continuous random variables. We show that reconciliation is a special case of channel coding and that existing coded modulation techniques can be adapted for reconciliation. We describe an explicit reconciliation method based on LDPC codes in the case of c...
متن کاملBlind reconciliation
Information reconciliation is a crucial procedure in the classical post-processing of quantum key distribution (QKD). Poor reconciliation efficiency, revealing more information than strictly needed, may compromise the maximum attainable distance, while poor performance of the algorithm limits the practical throughput in a QKD device. Historically, reconciliation has been mainly done using close...
متن کاملProblems in application of LDPC codes to information reconciliation in quantum key distribution protocols
The information reconciliation in a quantum key distribution protocol can be studied separately from other steps in the protocol. The problem of information reconciliation can be reduced to that of distributed source coding. Its solution by LDPC codes is reviewed. We list some obstacles preventing the LDPC-based distributed source coding from becoming a more favorable alternative to the Cascade...
متن کاملEasily Implemented Rate Compatible Reconciliation Protocol for Quantum Key Distribution
Reconciliation is an important step to correct errors in Quantum Key Distribution (QKD). In QKD, after comparing basis, two legitimate parties possess two correlative keys which have some differences and they could obtain identical keys through reconciliation. In this paper, we present a new rate compatible reconciliation scheme based on Row Combining with Edge Variation (RCEV) Low Density Pari...
متن کاملEfficient Rate-Adaptive Reconciliation in Quantum Key Distribution
The purpose of reconciliation, one of classical aspects of quantum key distribution (QKD) protocol, is to mitigate errors after the distribution of quantum information over a quantum channel. In this work, a rate-adaptive method is proposed by means of a channel coding scheme where specific low-density parity-check (LDPC) codes are adapted in the Slepian-Wolf coding system. In order to estimate...
