Quantum computers will revolutionise secure communications, and will make some current encryption methods obsolete. This activity, takes in cutting-edge research at the UK Quantum Technology hubs but begins with a firm grounding in the fundamentals of encryption. Unplugged activities will help students to understand basic shift ciphers and public-key encryption such as RSA.
Simulations and theoretical models are included, which explore the quantum encryption methods that will be necessary to keep data safe from prying eyes. It will be of interest to students of computer science, physics and, especially, both.
