Configuration of three resonators connected located in triangular scheme is considered for implementation of single and two-qubit gates. Each of the resonators can be coupled with its three-level atom and with neighbor resonator in defined moment of time. The regimes for coherent control of atom-photonic molecule states in the studied scheme and realization of single- and two qubit gates on this basis are theoretically investigated. The two qubit gate is considered in two various regimes: at the sequential switching on the interactions with step by step transfer of excitation and when central resonator is coupled simultaneously with two side resonators and excitation is transferring in the course of single process. Comparison of these two approaches is performed and recommendations for the construction of quantum computers on the atom-photon molecular states are presented.
