The first public demonstration on optical fiber in three countries was held today in Trieste during the G20 on digitization with an innovative encryption system. Professor Bassi: Very high levels of security
Those who were there attended a video call between Trieste (Italy), Ljubljana (Slovenia) and Rijeka (Croatia) and a live concert of three quartets. The particularity that this was the first public demonstration of an international quantum communication on optical fiber, in the presence of the ministers Giancarlo Giorgetti (Economic development) and Vittorio Colao (Technological innovation and digital transition), on Thursday morning in the context of the G20 on digitization held on Thursday in the Julian capital.
Photons
The communication made use of an innovative anti-hacker quantum cryptography: a sequence of random numbers generated at a distance through the exchange of photons. In practice, for himself a hacker tries to intercept the communication, leaves a trace that allows to detect the intrusion and intervene immediately. The experimentation, which is unprecedented because it took place through three network nodes in three different countries with fiber optic connections by Tim and Sparkle, preparatory to the future European quantum communication infrastructure (EuroQCI), promoted by the 27 Member States and the European Commission , with the support of the European Space Agency (ESA).
Anti-hacker
Quantum technology guarantees very high levels of security thanks to encrypted keys, explains Angelo Bassi, professor of the Physics department of the University of Trieste, who has just published on Nature a comment on the development of quantum experiments in celestial space. The exchange of quantum keys, thanks to the technologies we developed in the laboratory to investigate the puzzles posed by quantum physics, can now be implemented on commercial optical fibers, added Alessandro Zavatta, head of the quantum communications group of the National Institute of Optics. of the Cnr.
