The availability of quantum annealing devices with hundreds of qubits has made the experimental demonstration of a quantum speedup for optimization problems a coveted, albeit elusive goal. Going beyond earlier studies of random Ising problems, here we introduce a method to construct a set of frustrated Ising-model optimization problems with tunable hardness. We study the performance of a D-Wave Two device (DW2) with up to 503 qubits on these problems and compare it to a suite of classical… Expand
Practical engineering of hard spin-glass instances
Recent technological developments in the field of experimental quantum annealing have made prototypical annealing optimizers with hundreds of qubits commercially available. The experimentalExpand
Seeking Quantum Speedup Through Spin Glasses: The Good, the Bad, and the Ugly
TLDR
This work proposes to complement head-to-head scaling studies that compare quantum annealing machines to state-of-the-art classical codes with an approach that compares the performance of different algorithms and/or computing architectures on different classes of computationally hard tunable spin-glass instances. Expand
Readiness of Quantum Optimization Machines for Industrial Applications
TLDR
Although the results show that transverse-field quantum annealing is outperformed by state-of-the-art classical optimization algorithms, these benchmark instances are hard and small in the size of the input, therefore representing the first industrial application ideally suited for testing near-term Quantum annealers and other quantum algorithmic strategies for optimization problems.

Demonstration of a Scaling Advantage for a Quantum Annealer over Simulated Annealing
TLDR
The first example of a scaling advantage for an experimental quantum annealer over classical simulated annealing is established: it is found that the D-Wave device exhibits certifiably better scaling than simulatedAnnealing, with $95\%$ confidence, over the range of problem sizes that the authors can test.

Advantages of Unfair Quantum Ground-State Sampling
TLDR
This work examines the power of quantum annealers to provide a different type of quantum enhancement of practical relevance, namely, their ability to serve as useful samplers from the ground-state manifolds of combinatorial optimization problems. Expand
Unraveling Quantum Annealers using Classical Hardness
TLDR
A general method to quantify the performance of quantum annealers on optimization problems suffering from varying degrees of temperature chaos is devised and finds, surprisingly, that its performance scales unfavorably as compared to several analogous classical algorithms. Expand
How Small-World Interactions Can Lead to Improved Quantum Annealer Designs
There are many factors that influence the design of quantum annealing processing units. Here we address the issue of improving quantum annealing processing unit designs from the point of view of theExpand
Analog errors in quantum annealing: doom and hope
TLDR
It is shown that J-chaos causes a catastrophic failure of quantum annealing, in that the scaling of the time-to-solution metric becomes worse than that of a deterministic (exhaustive) classical solver, and this doomsday scenario can be mitigated using a simple error suppression and correction scheme known as QAC.

Inhomogeneous driving in quantum annealers can result in orders-of-magnitude improvements in performance
Quantum annealers are special-purpose quantum computers that primarily target solving Ising optimization problems. Theoretical work has predicted that the probability of a quantum annealer ending inExpand
Enhancing quantum annealing performance for the molecular similarity problem
TLDR
This work investigates the performance of a quantum annealer in solving the molecular similarity problem and provides experimental evidence that common practices for embedding can be replaced by new alternatives which mitigate some of the hardware limitations and enhance its performance. Expand
