Abstract

We propose a composite frequency-scalable quantum memory (QM) scheme based on a system of coupled resonators with single atoms capable of efficient storage of the quantum states of broadband single-photon fields having an arbitrary time form. The analyzed QM consists of 8 high-Q miniresonators coupled to a common resonator that is connected to the external waveguide, where each miniresonator contains a single atom. Based on the methods of optimization of the transfer function, we found the optimal parameters of the QM scheme at which an efficient transfer of a photon wave packet from an external waveguide to the atoms is possible for efficient long-term storage in long-lived atomic states. Various functional modes of using the memory circuit are described and ways to increase efficiency for its use in quantum processing are discussed.
