Today’s society is based on fast information exchange done via optical communication in fibers. However, not only does the current structure of our network consume tremendous amounts of energy, the data transfer is fundamentally insecure. Therefore, we urgently need a future network with increased energy efficiency while allowing for secure data communication. The solution lies in quantum physics, which makes it possible to encode information on a single-photon. This allows for totally secure communication due to the no-cloning theorem. Security of data and protection against eavesdropping is of crucial importance for our society, in which personal data and identity theft as well as cyber-attacks threatens the integrity and sovereignty of whole countries. Quantum Repeaters using On-demand Photonic Entanglement (Qurope) will develop the missing crucial technology to bring quantum communication to market, making secure communication finally reality.
