 Quantum key distribution using solid-state single-photon emitters has been shown to be feasible for long-distance applications. By optimizing the system parameters, it was possible to achieve a key generation rate of 13 kilobits per second after only one minute of data collection. This is a significant improvement from previous results which were limited to a few hundred bits per second. Additionally, the use of a more stringent statistical analysis showed that the previously reported finite key rates were significantly overestimated. This article was authored by Christopher L.
