The rise of quantum computers poses a significant threat to the security of optical communications. A sufficiently powerful quantum computer could render today’s public key cryptographic methods ineffective, exposing data in transit. However, with the development of quantum-safe encryption methods, including post-quantum cryptography (PQC) and quantum key distribution (QKD), networks can be made secure against quantum-enabled attacks.
In this short course, Helmut Grießer and Andrew Shields present a crash course in quantum-safe cryptography aimed at audiences without prior knowledge of encryption and key distribution. They will explain the applications of quantum-safe encryption along with the basic principles and benefits of the technology. They will also explore factors limiting the performance of today’s quantum encryption systems.
