Working on this project has been a joyful, collaborative venture. Our collaborators represent a diverse list of people, aged 7 to 75+, from both inside and outside the QET Labs team. All involved have helped shape our conversation about light, its particles, and the past, present and future of quantum cryptography and communication.

Volume 1

Our story is about the journey of cryptography, mathematics, physics and optics through time, from the first recorded cryptography device in Europe- SKYTALE, notably used in ancient Sparta, to today's quantum information hubs and research centres.

From ancient Sparta, Al-Khwarizmi's Baghdad, Alhazen's Cairo and Ibn Sina's Shah-e Rey, through the World War Two Resistance movements, with a pit-stop at Massachusetts Institute of technology, we arrive at 2019. There, we look at what the development of quantum cryptography, pondering how to go about it.
