Abstract

Abstract: We propose a scheme for a programmable quantum motherboard based on a system of three interacting high-Q resonators coupled with two-level atoms. By using algebraic methods, we found that the investigated atomic-resonator platform can possess an equidistant spectrum of eigenfrequencies at which the simple reversible dynamics of single photon excitation becomes possible. It was shown that such a multiresonator quantum motherboard scheme allows us to achieve an efficient and programmable quantum state transfer between distributed atoms and generate logical qubits and qutrits. The use of the studied circuit in quantum processing is proposed.
