Quantum-accelerated constraint programming
Kyle E. C. Booth, Bryan O'Gorman, Jeffrey Marshall +2
Constraint programming (CP) is a paradigm used to model and solve constraint satisfaction and combinatorial optimization problems. In CP, problems are modeled with constraints that…
Comparing relaxation mechanisms in quantum and classical transverse-field annealing
Tameem Albash, Jeffrey Marshall
Annealing schedule control provides new opportunities to better understand the manner and mechanisms by which putative quantum annealers operate. By appropriately modifying the ann…
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…
Augmented fidelities for single qubit gates
Filip Wudarski, Jeffrey Marshall, Andre Petukhov +1
An average gate fidelity is a standard performance metric to quantify deviation between an ideal unitary gate transformation and its realistic experimental implementation. The aver…
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…
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…
