Unlike classical key distribution, the presence of an eavesdropper can be detected by two communicating users. Experimental quantum key distribution has been performed over distances in the order of 100 km in standard telecom fibres as well as in free space.

According to the quantum technologies and space report prepared by the EPO and the European Space Policy Institute (ESPI) in collaboration with the European Space Agency (ESA), quantum key distribution is currently the leading application in space-related quantum technologies. More than 77% of the identified space-related quantum technology patent filings relate to this application, which largely accounts for an overall growth in space-related quantum technology patent filings between 2015 and 2020.
According to the report, there is a clear sense of urgency to develop new secure communication methods, in the wake of...
