Trap System

We present an alternative scheme for generating the N-qubit cluster state in the ion trap system. This scheme is based on adiabatic passage and thus is insensitive to the small fluctuations of the system parameters. During the process of evolution, quantum information transfer occurs only between the ions, and the collective vibrational mode remains in the vacuum state without excitation. Thus, the scheme is robust against phonon decoherence.

Trap System

We propose a method to accelerate the revival of ion Rabi oscillation in a trapped ion system. Suitable manipulation of the frequency of the driven laser field permits us to switch from Jaynes–Cummings to off-resonant interaction. The combination of Jaynes–Cummings model and the off-resonant model induces some interesting characteristics of the ion-trap system, particularly the accelerated revival of the population of trapped ions. The amplitude of this revival is sensitive to the change of the laser frequency.

Swap Gate

We propose an experimentally feasible scheme for implementing a two-ion swap gate in the context of the ion-trap system. In this scheme, we drive the ion with one laser beam and we map the states of one ion and the motional mode to each other. The scheme is based on resonant sideband excitation, and thus it may be realized with current ion-trap techniques.
