QKD Post-Processing software

SeQureNet makes its QKD post-processing software available to academic institutions, enabling them to focus on their core know-how in quantum physics. High Efficiency (capacity of the error-corrected channel above 90% of the Shannon bound), high speed error correction for a wide range of SNRs, and fast privacy amplification are provided. Error correction does not require many interactions since it uses error-correction codes (LDPC or polar) instead of multiple-pass algorithms such as Cascade.

Cygnus: State-of-the-art CVQKD module

SeQurenet CVQKD module, using the Gaussian protocol and able to work at very low SNRs, considerably improves the maximum operating range of CVQKD, from 25Km in previous experiments to about 80Km. The equipment is composed of two optical boxes, Alice and Bob, and two supporting PCs for protocol management, error correction, and distillation. It can be used for IT security or network experimentation, and also for scientific research.
