A practical heuristic for finding graph minors
TL;DR: A heuristic algorithm for finding a graph H as a minor of a graph G that is practical for sparse $G$ and $H$ with hundreds of vertices is presented.
Journal ArticleDOI
Equiangular lines, mutually unbiased bases, and spin models
Chris Godsil,Aidan Roy +1 more
TL;DR: It is shown how to construct difference sets from commutative semifields and that all known maximal sets of mutually unbiased bases can be obtained in this way, resolving a conjecture about the monomiality of maximal sets.
Journal ArticleDOI
Fast clique minor generation in Chimera qubit connectivity graphs
TL;DR: A combinatorial class of native clique minors in Chimera graphs with vertex images of uniform, near minimal size are defined and a polynomial-time algorithm is provided that finds a maximumnative clique minor in a given induced subgraph of a Chimera graph.
Journal ArticleDOI
Discrete optimization using quantum annealing on sparse Ising models
TL;DR: A way of finding energy representations with large classical gaps between ground and first excited states, efficient algorithms for mapping non-compatible Ising models into the hardware, and the use of decomposition methods for problems that are too large to fit in hardware are proposed.

Next-Generation Topology of D-Wave Quantum Processors
TL;DR: This paper presents an overview of the topology of D-Wave's next-generation quantum processors and provides examples of minor embeddings and discusses performance of embedding algorithms for the new topology compared to the existing Chimera topology.
