Part I starts from established knowledge and takes us via Kepler, Newton, Einstein, Planck and Heisenberg into the fascinating quantum world and the speculative ideas it opens up. Are space and time fundamental? At a deeper level, is reality made of things or of relationships? And what role does information play in what we call reality.

Our upcoming Part II covers quantum computers, post-quantum cryptography, quantum key distribution, network security, digital sovereignty, quantum repeaters and the long-term prospect of a quantum internet. At its core is the question of what telecommunications companies in particular need to understand and prepare today in order to remain secure and sovereign in a quantum technology future.
