Abstract

The requirements of the mass consumer and educational market impose great restrictions on the cost of hardware-software demonstrators with relatively low requirements for the characteristics of the quantum key distribution process. This means that these devices do not have to be advanced and, as such, can provide a dramatic reduction in size, weight, and power compared to other quantum key distribution systems. The article presents the stages of development and creation of an experimental prototype of a hardware-software demonstrator of a universal quantum key distribution system that implements existing methods based on amplitude and phase modulation, as well as the proposed method of tandem amplitude-phase modulation of an optical carrier. The evaluation of the technical, economic and operational characteristics of the hardware-software demonstrator was carried out; practical recommendations were formulated for its development, creation and operation, as well as for the choice of an import-substituting element base, which ensured its low cost and the possibility of wide use at various research and educational sites, including World Skills youth championships and Future Skills process. In addition, the proposed demonstrator, embedded in a desktop computer, can act as access devices that can be connected to a terminal combined with a quantum network node to replenish a secret key store, which can then be used to encrypt daily activities on conventional platforms such as the Internet.
