100 Mbps Reconciliation for Quantum Key Distribution Using a Single Graphics Processing Unit

An efficient error reconciliation scheme is important for post-processing of quantum key distribution (QKD). This paper concerns the improvement performance. Recently, a multi-matrix low-density parity-check code-based algorithm which can provide remarkable perspectives high-efficiency information was proposed by Gao (Opt Express 27:14545–14566, 2019). The implemented and optimized on graphics processing unit (GPU) to obtain high throughput. Experimental results indicate that GPU-based highly improve throughput an average 85.67 Mbps maximum 102.084 with typical code rate efficiency. best performance GPU platform our knowledge.
