Abstract
We propose a hybrid quantum repeater based on ancillary coherent field states and material qubits coupled to optical cavities. For this purpose, resonant qubit-field interactions and postselective field measurements are determined which are capable of realizing all necessary two-qubit operations for the actuation of the quantum repeater. We explore both theoretical and experimental possibilities of generating near-maximally-entangled qubit pairs () over long distances. It is shown that our scheme displays moderately low repeater rates, between and 23 pairs per second, over distances up to 900 km, and it relies completely on current technology of cavity quantum electrodynamics.
