Entangled states are a resource for quantum computing and quantum sensing. We have proposed a new method of generating entangled states of multiple atoms which uses an optical cavity and achieves a fidelity which is exponentially better than similar prior methods [1]. The method is called ‘counterfactual carving’ and relies on no-jump evolution. We will integrate novel optical cavities with neutral atom arrays and explore creating entangled graph states of neutral atoms, which can be fused together to form cluster states for measurement-based quantum computing.
