Deterministic generation of entangled photonic cluster states from quantum dot molecules*

Successful generation of photonic cluster states is the key step in the realization of quantum networks and measurement-based quantum computation. In this work, we propose the deterministic generation of these photonic cluster states from quantum dot molecules: A pair of vertically stacked quantum dots. Our proposal, based on the hole spin qubits, takes advantage of the unique control scheme of this platform and resolves many of the difficulties of available protocols. Our new proposal paves the way for an experimentally feasible realization of highly entangled multi-qubit photonic states.
