Research of leading companies in the development of the global quantum communications market

Abstract

Quantum technologies have the potential to transform the telecommunications industry. The quantum communications industry is already moving from the stage of scientific research to commercial application in Russia, China, the USA, Singapore and a number of other countries. The authors set a goal to identify the main leaders in the development of quantum communications in the world, to identify their characteristic properties. As a result of the analysis of revenue and R&D costs of companies, patent activity and information on pilot projects in the field of quantum communications, we found that equipment manufacturers demonstrate slightly greater R&D activity than telecommunications companies, which may indicate the consolidation of their technological leadership not only in traditional but also in new markets. The indicators of the share of R&D costs, total patent activity and geographic location of telecommunications equipment manufacturers do not correlate with the practice of participation in piloting quantum communications technologies.
