Low-Dimensional Reconciliation for Continuous-Variable Quantum Key Distribution
We propose an efficient logical layer-based reconciliation method for continuous-variable quantum key distribution (CVQKD) to extract binary information from correlated Gaussian variables. We demonstrate that by operating on the raw-data level, the noise of the quantum channel can be corrected in the low-dimensional (scalar) space, and the reconciliation can be extended to arbitrary dimensions....
متن کاملInformation Reconciliation for Continuous-Variable Quantum Key Distribution using Non-Binary Low-Density Parity-Check Codes
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 ...
متن کاملScalar Reconciliation for Gaussian Modulation of Two-Way Continuous-Variable Quantum Key Distribution
The two-way continuous-variable quantum key distribution (CVQKD) systems allow higher key rates and improved transmission distances over standard telecommunication networks in comparison to the one-way CVQKD protocols. To exploit the real potential of two-way CVQKD systems a robust reconciliation technique is needed. It is currently unavailable, which makes it impossible to reach the real perfo...
متن کاملSingle-quadrature continuous-variable quantum key distribution
Most continuous-variable quantum key distribution schemes are based on the Gaussian modulation of coherent states followed by continuous quadrature detection using homodyne detectors. In all previous schemes, the Gaussian modulation has been carried out in conjugate quadratures thus requiring two independent modulators for their implementations. Here, we propose and experimentally test a largel...
