Generating spatially distributed entanglement as a resource for novel quantum computing paradigms on a platform of coupled microcavities — •Marc Bostelmann, Steffen Wilksen, Frederik Lohof, and Christopher Gies — Institute for Theoretical Physics and Bremen Center for Computational Material Science, University of Bremen, Bremen, Germany

Spatially distributed entanglement is important for the realization of novel quantum-photonic applications in quantum computing and quantum machine learning. We consider photonic arrays made from quantum emitters in optically coupled microcavities as hardware platform for entanglement generation. These offer a large degree of tunability with the possibility of site-selective optical excitation. We present a scalable numerical scheme for the determination of excitation parameters to generate different classes of multipartite entangled states, and a quantum bath engineering approach to create entanglement in the steady-state [arXiv:2211.13639].
