| Efficient polar encoding for information reconciliation in QKD | QCRYPT 2023 | Snehasis Addy, Somnath Panja, Sabyasachi Dutta, Daniel Oblak |
Quantum Key Distribution (QKD) enables two parties to establish common secret keys by transmitting bits encoded in quantum systems (qubits), which provides unconditional security. QKD introduces errors during quantum communication, which need to be corrected post-key exchange. Typical error-correcting codes in the context of QKD include Cascade, Low-density parity check (LDPC) codes, and polar codes. In our work, we use polar codes, which are state-of-the-art error-correcting codes meeting the requirements of a QKD system. We provide an implementation of an encoder for polar codes based on reliability sequence, which is computationally efficient and can be implemented in QKD postprocessing. Our work on improving the efficiency of QKD postprocessing is highly relevant for the commercialization of QKD. |
