Deterministic generation of qudit photonic graph states from quantum emitters — •Zahra Raissi1,2, Edwin Barnes2, and Sophia E. Economou2 — 1Paderborn University, Paderborn, Germany — 2Virginia Tech, Virginia, USA
We propose and analyze deterministic protocols to generate qudit photonic graph states from quantum emitters. We show that our approach can be applied to generate any qudit graph state, and we exemplify it by constructing protocols to generate one- and two-dimensional qudit cluster states, 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. The only additional resource requirement compared to the qubit case is the ability to control multi-level emitters. These results significantly broaden the range of multi-photon entangled states that can be produced deterministically from quantum emitters and open up new possibilities for quantum information processing.
