Quantum communication represents an innovative technology in secure data transmission, leveraging the principles of quantum mechanics to ensure unparalleled security. Traditional communication methods such as fibre optics face limitations, due to long-range signal attenuation. In contrast, free-space transmission of photons through space, encounters minimal interference, enabling data to travel vast distances without significant loss.
A study by Yin et al. ( Yin, Juan, et al. “Satellite-based entanglement distribution over 1,200 kilometers.” Science 356.6343 (2017): 1140-1144) demonstrated the feasibility of satellite-based quantum communication by distributing entangled photon pairs over 1,200 kilometres between two ground stations. This achievement underscores the potential of satellites with quantum sources to facilitate global-scale quantum-secure communications.
HellasQCI is at the forefront of implementing quantum-secure networks across various sectors:
