Phys. Rev. Lett. 82, 1835–1838 (1999)Multiparticle Entanglement of Hot Trapped IonsReceived 13 October 1998; published in the issue dated 1 March 1999 We propose an efficient method to produce multiparticle entangled states of ions in an ion trap for which a wide range of interesting effects and applications have been suggested. Our preparation scheme exploits the collective vibrational motion of the ions, but it works in such a way that this motion need not be fully controlled in the experiment. The ions may, e.g., be in thermal motion and exchange mechanical energy with a surrounding heat bath without detrimental effects on the internal state preparation. Our scheme does not require access to the individual ions in the trap. © 1999 The American Physical Society URL:
