Concept 25Quantum dots as single-photon sourcesConfined electronic states can emit antibunched photons on demand.Concept 26Color centers and solid-state spinsPoint defects can combine optical transitions with long-lived spin degrees of freedom.Concept 27Single-photon indistinguishabilityIdentical wavepackets are essential for high-visibility two-photon interference.Concept 28Hong–Ou–Mandel interferenceTwo indistinguishable photons entering a balanced beamsplitter leave together.Concept 29Spontaneous parametric down-conversionA second-order nonlinear medium can convert a pump photon into correlated signal and idler photons.Concept 30Spontaneous four-wave mixingThird-order nonlinearities generate photon pairs in fibers and integrated waveguides.Concept 31Entangled photon pairsPhotonic polarization, path, time-bin or frequency modes can share nonseparable states.Concept 32Linear optical quantum computingSingle photons, interferometers and measurements support photonic quantum information processing.
