Entanglement and Phase-Covariant Cloning for Multiple Trapped Ions via Adiabatic Passage
LU Dao-ming, Zheng Shi-Biao · Communications in Theoretical Physics · 2008
We describe a scheme for the generation of W states and implementation of phase-covariant cloning for n trapped ions. The scheme does not use the vibational mode as the memory and works beyond the Lamb-Dicke regime. The procedure is robust against moderate fluctuations of experimental parameters by using adiabatic passage.
