Quantum Key Distribution (QKD) vs. Post-Quantum Cryptography (PQC) – by Rupert Ursin
Even a new kind of software-based cryptography, such as Post-Quantum Cryptography (PQC), does not solve the problem, as it (again!) relies on assumptions about the hacker. Physics-based Quantum Key Distribution (QKD) does not!
Today, encryption protects emails, financial transactions, and much more, but it is at risk from quantum computers. These powerful machines can exploit quantum physics to solve complex problems, including those at the heart of public key encryption, such as RSA. Although Y2Q has not yet arrived, experts estimate that it could do so in 6 years.
