Quantum-dot based photonic quantum networks

Quantum dots embedded in photonic nanostructures have in recent years proven to be a very powerful solid-state platform for quantum optics experiments.The combination of near-unity radiative coupling of a single quantum dot to a photonic mode and the ability to eliminate decoherence processes imply that an unprecedent light-matter interface can be obtained.As a result, high-cooperativity photonemitter quantum interfaces can be constructed opening a path-way to deterministic photonic quantum gates for quantum-information processing applications.In the present manuscript, I review current state-of-the-art on quantum dot devices and their applications for quantum technology.The overarching long-term goal of the research field is to construct photonic quantum networks where remote entanglement can be distributed over long distances by photons.
