In particular, we study possible generalizations of an optical setup proposed in Sedlák [Phys. Rev. A 76, 022326 (2007)]. We show how the unambiguous identification of coherent states can be performed in a general...<br/>[Phys. Rev.

Bermudez, D. Porras, and M. A. Martin-Delgado<br/>We propose and theoretically analyze an experimental configuration in which lasers induce three-spin interactions between trapped ions. By properly choosing the intensities and frequencies of the lasers, three-spin couplings may be dominant or comparable to two-spin terms and magnetic fields.

We introduce adaptive teleportation, i.e., such that the choice of entangled state used in the next teleportation depends on the results of the measurements performed during the previous teleportations. We show that adapt...<br/>[Phys. Rev.
