Future quantum computers will be no match for 'space encryption' that uses light to beam data around — with the 1st satellite launching in 2025
Quantum computers will break encryption one day. But converting data into light particles and beaming them around using thousands of satellites might be one way around this problem.
For example, in a paper published Jan. 21 in the journal Advanced Quantum Technologies, scientists describe a mission called "Quick3," which uses photons — particles of light — to transmit data through a massive satellite network. "Security will be based on the information being encoded into individual light particles and then transmitted," Tobias Vogl, professor of quantum communication systems engineering at TUM and co-author of the paper, said in a . The challenge with traditional Earth-based quantum cryptography, however, lies in transmitting data over long distances, with a maximum range of just a few hundred miles, the TUM scientists said in the statement.
