The development of quantum computers poses a significant threat to today’s communication security, since it currently relies solely on the time-consuming process of breaking algorithms used for its establishment. However, in the advent of sufficiently powerful quantum computers, these algorithms could be effectively broken by executing the so-called Shor’s algorithm on the forementioned computer, which would undermine communication security as a whole. Due to this major challenge, new approaches for achieving secure communication have begun to be considered. One potential solution is Quantum Key Distribution (QKD). Therefore, this paper presents an experimental quantum key distribution system based on the BB84 protocol and its corresponding physical setup. For protocol implementation, components such as 810 nm wavelength photon sources, single-photon avalanche diode (SPAD) detectors, and G.652.D telecommunication optical fiber were utilized. It is demonstrated how telecommunication fiber and SPAD detectors can be successfully employed for quantum key distribution over short distances, thus opening the possibility of a more cost-effective protocol implementation in the future. The protocol was successfully implemented for attenuation up to 8.3 dB, corresponding to the length of 2.7 km of optical fiber. The protocol and results mentioned in this summary were also presented in an article titled “Near Infrared Devices and Protocols for Short Distance Quantum Key Distribution via Telecom Fibers” at MIPRO hybrid international convention and will be available in the IEEE Xplore database.
