Analysis of RKER and QBER parameters of interferometric architecture QKD system under controlled perturbation of quantum communication channel.
Raw Key Exchange Rate RKER and Quantum Bit Error Rate QBER parameters characterization of interferometric architecture QKD system. Measurement were performed under controlled perturbation of quantum communication channel. Perturbations were model as real loses which occurs in commercial telecom optic fibers – in laboratory environment various number of connectors and patchcords were used to simulate loses of welding and commercial fiber connections. Results have been analyzed with X-R Shewhart control cards.
