摘要/Abstract

摘要： An experimentally realizable physical scheme for preparing multiqubit cluster states from a large detuned atom--cavity interaction is proposed. The scheme is free of any type of measurement and insensitive to the cavity decay, and the cavity field is only virtually excited so that there is no information exchanging between atom and cavity. The time required for the gate operations is very short, which is important for decoherence. We also discuss the experimental feasibility of our scheme.

The time required for the gate operations is very short, which is important for decoherence. We also discuss the experimental feasibility of our scheme.
