Abstract Passive decoy state quantum key distribution (PDS-QKD) has advantages in high-speed scenarios. We propose a modified model to simulate the PDS-QKD with a weak coherent light source based on Curty's theory [Opt. Lett.34 3238 (2009)]. The modified model can provide better performance in a practical PDS-QKD system. Moreover, we report an experimental demonstration of the PDS-QKD of over 22.0-dB channel loss.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
