Abstract This paper presents a scheme for probabilistic remote preparation of a three-particle entangled Greenberger--Horne--Zeilinger (GHZ) state via three-particle orthonormal basis projective measurement, and then directly generalize the scheme to multi-particle case. It is shown that by using $N$ pairs of bipartite non-maximally entangled states as the quantum channel and $N$-particle orthonormal basis projective measurement, the multi-particle remote preparation can be successfully realized with a certain probability.

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.
