We propose a simple scheme for deterministic and multi-controlled teleportation of an arbitrary unknown two-level two-ion state in ion-trap system. In the scheme, the special entangled W states used as quantum channel...

We propose a scheme for generating a four-particle cluster state in an ion-trap system.The scheme isinsensitive to the thermal motion of the ions,and needs less operations than previous ones.With such a setup,we alsod...
