Ion trap quantum gates with amplitude-modulated laser beams
2008
New Journal of Physics
In ion traps, entangling gate operations can be realized by a bichromatic pair of laser beams that collectively interact with the ions. In this paper, a new method of modelling the laser-ion interaction is introduced that turns out to be superior to standard techniques for the description of gate operations on optical qubits. The treatment allows for a comparison of the performance of gates based on σ_z⊗σ_z and Mølmer-Sørensen interactions on optical transitions where the bichromatic laser
