Abstract A scheme is proposed for generating multiparticle three-dimensional entangled state by appropriately adiabatic evolutions, where atoms are respectively trapped in separated cavities so that individual addressing is needless. In the ideal case, losses due to the spontaneous transition of atom and the excitation of photon are efficiently suppressed since atoms are all in ground states and the fields remain in vacuum state. Compared with the previous proposals, the present scheme reduces its required operation time via simultaneously controlling four classical fields. This advantage would become even more obvious with the number of atoms increasing. The experimental feasibility is also discussed. The successful preparation of high-dimensional multiparticle entangled state among distant atoms provides better prospects for quantum communication and distributed quantum computation.

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.
