Hidden anisotropy controls spin-photon entanglement in a charged quantum dot
Measurement-based quantum computing, vital for scalable photonic quantum technologies, is limited by inefficient generation of high-fidelity cluster states from spin-photon entanglement in semiconductor quantum dots. This work explores the deep connections between quantum dot spin physics and quantum optics, leading to the discovery of strong anisotropy in the entanglement process and identification of optimal entanglement conditions to improve cluster-state fidelity. That insight enables improved cluster-state sources, advancing optical quantum computing and quantum networks.
