In this paper we present a remote state preparation scheme with a three-qubit W-class state in cavity QED. It has
been shown that a special single-qubit state and a special two-qubit entangled state can be remotely prepared perfectly.
Furthermore, the classical information cost in this scheme is less than that in the corresponding teleportation scheme
and only a single-qubit projective measurement is made by the sender. We also generalize this idea to the multiqubit W-class state.

Fund: In this paper we present a remote state preparation scheme with a
three-qubit $W$-class state in cavity QED. It has been shown that a
special single-qubit state and a special two-qubit entangled state
can be remotely prepared perfectly. Furthermore, the classical
information cost in this scheme is less than that in the
corresponding teleportation scheme and only a single-qubit
projective measurement is made by the sender. We also generalize
this idea to the multiqubit $W$-class state.

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.
