(TimesOfMalta) Researchers from the Austrian Academy of Sciences and the University of Vienna have established a quantum encrypted connection between Malta and Sicily via a conventional underwater telecommunications cable using entangled light particles.
“This total distance of 192 kilometres is a new record for the method of producing quantum keys through polarisation-entangled light particles over longer distances on Earth. In this test setup, the transmission speed reached four bits per second” the researchers said.
The experiment at the bottom of the sea provided evidence of the unexpectedly high stability of the method and thus of the great potential it holds for the creation of a quantum internet of the future, by employing a conventional telecommunications infrastructure, they added.
