Abstract This paper proposes a scheme for entanglement swapping based on cavity QED. The two atoms to be entanglement-swapped can be separated over long distance. The scheme is a non-post-selection one with the success probability of 1/2.

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.
