Definitive review of linear optical quantum computing (LOQC). Covers the KLM scheme and subsequent improvements, including cluster-state approaches and error-correction protocols. Reviews single-photon sources, photon detectors, and integrated photonic platforms. Establishes the theoretical framework for scalable photonic quantum computing using linear optics, measurement, and feed-forward.
