Ferromagnetically shifting the power of pausing
Zoe Gonzalez Izquierdo, Shon Grabbe, Stuart Hadfield +3
We study the interplay between quantum annealing parameters in embedded problems, providing both deeper insights into the physics of these devices and pragmatic recommendations to…
Characterizing local noise in QAOA circuits
Jeffrey Marshall, Filip Wudarski, Stuart Hadfield +1
Recently Xue et al. [arXiv:1909.02196] demonstrated numerically that QAOA performance varies as a power law in the amount of noise under certain physical noise models. In this shor…
Optimizing quantum heuristics with meta-learning
Max Wilson, Sam Stromswold, Filip Wudarski +3
Variational quantum algorithms, a class of quantum heuristics, are promising candidates for the demonstration of useful quantum computation. Finding the best way to amplify the per…
From Ansätze to Z-gates: a NASA View of Quantum Computing
Eleanor G. Rieffel, Stuart Hadfield, Tad Hogg +12
For the last few years, the NASA Quantum Artificial Intelligence Laboratory (QuAIL) has been performing research to assess the potential impact of quantum computers on challenging…
Quantum Algorithms for Scientific Computing and Approximate Optimization
Stuart Hadfield
Quantum computation appears to offer significant advantages over classical computation and this has generated a tremendous interest in the field. In this thesis we consider the app…
