A02 – Generation of photonic cluster states from color center-cavity systems
Summary
Project A02 focuses on the investigation of highly correlated states of light and matter, here realized as a bottom-up toolbox for light-matter and light-light entanglement. The central basic element consists of an entangled state of a single photon and a single electron spin of an individual defect center in diamond. This basic element will be concatenated in time to create a highly cooperative quantum state of light, i.e., a photonic cluster state. Such a cluster state arises due to the collective coupling of subsequently emitted photons to a common degree of freedom, i.e., the entanglement with the same single electron spin. In a medium-term perspective quantum-cooperative effects will be used to create matter entanglement first and higher dimensional cluster states built from this resource.
