Efficient construction of photonic quantum-computational clusters
Gerald N. Gilbert, Michael Hamrick, Yaakov S. Weinstein · Physical Review A · 2006
We demonstrate a method of creating photonic two-dimensional cluster states that is considerably more efficient than previously proposed approaches. Our method uses only local unitaries and type-I fusion operations. The increased efficiency of our method compared to previously proposed constructions is obtained by identifying and exploiting local equivalence properties inherent in cluster states.
