Chip-based devices improve practicality of quantum-secured communication

Science Daily  March 19, 2020
A team of researchers in the UK present secure key exchange up to 200 km while removing all side-channels from the measurement system. They used mass-manufacturable, monolithically integrated transmitters that represent an accessible, quantum-ready communication platform. This work demonstrates a network topology that allows secure equipment sharing which is accessible with a cost-effective transmitter, significantly reducing the barrier for widespread uptake of quantum-secured communication…read more.
