Best-case performance of quantum annealers on native spin-glass benchmarks: How chaos can affect success probabilities
Zheng Zhu, Andrew J. Ochoa, Stefan Schnabel +2
Recent tests performed on the D-Wave Two quantum annealer have revealed no clear evidence of speedup over conventional silicon-based technologies. Here, we present results from cla…
Seeking Quantum Speedup Through Spin Glasses: The Good, the Bad, and the Ugly
Helmut G. Katzgraber, Firas Hamze, Zheng Zhu +2
There has been considerable progress in the design and construction of quantum annealing devices. However, a conclusive detection of quantum speedup over traditional silicon-based…
Efficient Cluster Algorithm for Spin Glasses in Any Space Dimension
Zheng Zhu, Andrew J. Ochoa, Helmut G. Katzgraber
Spin systems with frustration and disorder are notoriously difficult to study both analytically and numerically. While the simulation of ferromagnetic statistical mechanical models…
