Abstract
With bichromatic fields, it is possible to deterministically produce entang led states of trapped ions. In this paper we present a unified analysis of this process for both weak and strong fields, for slow and fast gates. Simp le expressions for the fidelity of creating maximally entangled states of t wo or an arbitrary number of ions under nonideal conditions are derived and discussed.
