The partners of the OPENQKD project including the Technical University in Ostrava, the Czech national supercomputing center IT4Innovations and the CESNET scientific network, as well as the Poznań Supercomputing and Networking Center (PSNC) and the PIONIER network conducted a successful test of data transmission secured with the quantum key distribution technology.
The quantum communication channel launched between Poland and the Czech Republic was connected with a 75 km long cross-border optical route between the nodes in Ostrava and Cieszyn. They have obtained a very good result with an average quantum bit error rate of 2.19 percent.
Data transmission secured by Quantum Key Distribution (QKD) technology is an important step in the development of secure telecommunications. QKD technology solves the problem of secure delivery of cryptographic keys and can be used for a number of services that require secure authentication, such as electronic payments.
