In Choi (Quantum Inf Process, 7:193-209, 2008), we introduced the notion of minor-embedding in adiabatic quantum optimization. A minor-embedding of a graph G in a quantum hardware graph U is a subgraph of U such that G can be obtained from it by contracting edges. In this paper, we describe the intertwined adiabatic quantum architecture design problem, which is to construct a hardware graph U that satisfies all known physical constraints and, at the same time, permits an efficient minor-embedding algorithm. We illustrate an optimal complete-graph-minor hardware graph. Given a family F of graphs, a (host) graph U is called F -minor-universal if for each graph G in F contains a minor-embedding of G. The problem for designing a F -minor-universal hardware graph U sparse in which F consists of a family of sparse graphs (e.g.; bounded degree graphs) is open. © 2010 Springer Science+Business Media, LLC.
