Abstract
We proposed a model for a controlled single-photon beam-splitter which can route photons with near-unity efficiency. It consists of two crossed optical-cavities with overlapping waists, dynamically coupled to a single flying atom in an effective weak-coupling regime. The two such nodes, forming a segment of a quantum network, are shown to perform several controlled quantum operations. This model can be extended to various other physical systems including gated quantum dots, circuit-QED and opto-mechanical systems.
