Deterministic generation of qudit photonic graph states from quantum emitters

Abstract

We propose and analyze deterministic protocols to generate qudit photonic graph states from quantum emitters. We exemplify our approach by constructing protocols to generate absolutely maximally entangled states and logical states of quantum error correcting codes. Some of these protocols make use of time-delayed feedback, while others do not. These results significantly broaden the range of multi-photon entangled states that can be produced deterministically from quantum emitters.Comment: 14 pages, 5 figure
