We experimentally demonstrate a long-distance quantum communication at 143 km between the city of Kazan and urban-type village Apastovo in Republic Tatarstan by using key distribution prototype providing high noise-immunity network lines nodes due to phase coding subcarrier wave. Average secret generation rate was 12 bits per second with losses line 37 decibels for distance during 16.5 hours continuous field test. The commercialization perspectives demonstrated long-range QKD system are discussed.
The study of noise generated by a system homodyne detection laser radiation was made when random is recorded at the outputs anoptical beam splitter after differential signals. We studied dependence parameters on length signal sequence sample and effect detrending using wavelet analysis. NIST test suite used to evaluate degree randomness sequence.
In this work, we study the timestamps in registration of single-photon detector counts quantum communications. The analysis afterpulse on basis several approaches is carried out. Robust diagnostics keys proposed to increase security networks.
In this paper, we formulate ideas for visual media trunk quantum networks with lines over 100 km. We investigate the local trends analysis of performance parameters experimental demonstration long-distance communication and discuss prospects commercialization quantum-classical cloud security services.
In this work, we study timestamps when registering counts of single-photon detectors in quantum communications. Post-pulse are analyzed based on several approaches. Explicit statistical accounting the noise allows you to most correctly select mode use realize efficient communication with highest signal ratio. Direct analysis and robust diagnostics can be done by ranging time's tags keys that available for online diagnostic system a significant amount information about performance (the dark...
In this paper, for the first time, we analyze real noise in a 143 km intercity quantum line which is based on original technical solution subcarrier wave key distribution system. The result of fundamental statistical analysis bit error rate presented. We draw initial conclusions stability and security communications provide recommendations online monitoring to increase communication security.
