In this work, we study the timestamps in the registration of single-photon detector counts in quantum communications. The analysis of afterpulse counts on the basis of several approaches is carried out. Robust diagnostics of keys is proposed to increase the security of quantum networks.
In this paper, we formulate ideas for visual media for trunk quantum networks with lines over 100 km. We investigate the local trends analysis of performance parameters for experimental demonstration of long-distance quantum communication and discuss the prospects of commercialization of quantum-classical cloud security services.
We propose a scheme of a programmable quantum motherboard based on the system of three interacting high-Q resonators coupled with two-level atoms. By using the algebraic methods, we found that the investigated atomic-resonator platform can possess an equidistant spectrum of the eigenfrequencies at which simple reversible dynamics of the single photon excitation becomes possible. It was shown that such multiresonator quantum motherboard scheme allows to achieve efficient and programmable quantum state transfer between distributed atoms and generate logical qubits and qutrits. The use of the studied circuit in quantum processing is proposed.
