Abstract In this paper, we accomplish the teleportation of an unknown three-particle maximally entangled $W$ state by using a spin-path entangled quantum channel which may be realized experimentally based on the advanced theory and technique in Bose--Einstein condensate (BEC) of molecule, micro-fabricated wave guide and simple quantum logic gate. Similarly, we can make an arbitrary $n$-particle entangled Greenberger--Horne--Zeilinger (GHZ) state ($n\ge 4$) teleported through this kind of quantum channel. It may have important applications due to its resource-economic and practical features.

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.
