ABSTRACT:

Non-classical states of light, such as single photons and entangled photon states, are essential for novel quantum technologies, including photonic quantum computing, quantum communications and key distribution, and the quantum internet. Large two-dimensional highly entangled ‘cluster’ states of photons are a class of so-called graph states which constitute a universal resource for quantum computing. Photons also carry information between nodes in a network, and photonic graph states can be used for such quantum networks. A crucial question is therefore how these states can be created efficiently. I will present our work focusing on the deterministic generation of photonic graph states from spinful quantum emitters for quantum computing and quantum networks.
