***Quantum dot–based time-bin QKD achieves stable, long-distance secure communication with practical performance.***
Â
Quantum key distribution is the most advanced area of quantum cryptography and offers fundamentally secure communication for the future quantum internet. Solid-state light sources such as semiconductor quantum dots (SQDs) have drawn significant attention because they can generate high-quality non-classical photons for quantum communication. These sources can support higher key generation rates and may enable the use of quantum repeaters.
