Quantum Expanders: Motivation and Constructions
... Their quantum expander is based on a Cayley expander over the Abelian group Zn2 . The main drawback of Cayley graphs over Abelian groups is that [26, 4] showed that such an approach cannot yield constant degree expanders. Indeed, this is reflected in the log2 N term in Theorem 1.3. There are constan ...
