| Summary: | Relevance. The upcoming widespread implementation of quantum technologies into the existing information and telecommunication infrastructure. Effective deployment is impossible without a preliminary analysis and justification of the adequacy and security of quantum key distribution systems. This, in its turn, necessitates the investigation and formalized comparison of the hardware architectures underlying these systems. An effective tool for addressing this challenge is computer modeling. Aim. To investigate, classify, and model typical hardware architectures of the quantum key distribution systems, as well as to verify the accuracy of the developed models. Object. Practical hardware architectures of the quantum key distribution systems. Methods. Mathematical modeling of optical systems based on Jones formalism, simulations in Simulink Matlab. Results. The authors have developed a simulation model of a typical quantum key distribution system utilizing the Plug-and-Play architecture. The model validity is confirmed by its robustness against polarization distortions in fiber-optic transmission. The developed optical component models in Simulink can also be applied to the simulation of other quantum key distribution system architectures. |
