- The next generation of global telecommunication systems will incorporate technological advances in manipulating the quantum nature of light. The use of entangled single photons enables quantum cryptography systems that provide ultimate information security based on fundamental laws of nature. We have demonstrated the world’s first LEDs emitting entangled photons at 1550nm and opened up applications in commercial fibre communications systems. This breakthrough was achieved in collaboration with industry and our LEDs have subsequently been used to demonstrate quantum teleportation in a fibre network. The work led to funding of an Industrial Strategy Challenge Fund project to commercialise quantum cryptography networks.
