Efficient generation of entangled multiphoton graph states from a single atom.

ABSTRACT: The central technological appeal of quantum science resides in exploiting quantum effects, such as entanglement, for a variety of applications, including computing, communication and sensing¹. The overarching challenge in these fields is to address, control and protect systems of many qubits against decoherence². Against this backdrop, optical photons, naturally robust and easy to manipulate, represent ideal qubit carriers. However, the most successful technique so far for creating photonic entanglement³ is inherently probabilistic and, therefore, subject to severe scalability limitations. Here we report the implementation of a deterministic protocol^4-6 for the creation of photonic entanglement with a single memory atom in a cavity⁷. W
