Classical symmetries and the Quantum Approximate Optimization Algorithm

no code implementations8 Dec 2020 Ruslan Shaydulin, Stuart Hadfield, Tad Hogg, Ilya Safro

Our approach formalizes the connection between quantum symmetry properties of the QAOA dynamics and the group of classical symmetries of the objective function.

Optimizing quantum heuristics with meta-learning

no code implementations8 Aug 2019 Max Wilson, Sam Stromswold, Filip Wudarski, Stuart Hadfield, Norm M. Tubman, Eleanor Rieffel

Variational quantum algorithms, a class of quantum heuristics, are promising candidates for the demonstration of useful quantum computation.

Bayesian Optimization Meta-Learning

From the Quantum Approximate Optimization Algorithm to a Quantum Alternating Operator Ansatz

no code implementations11 Sep 2017 Stuart Hadfield, Zhihui Wang, Bryan O'Gorman, Eleanor G. Rieffel, Davide Venturelli, Rupak Biswas

The essence of this extension, the Quantum Alternating Operator Ansatz, is the consideration of general parametrized families of unitaries rather than only those corresponding to the time-evolution under a fixed local Hamiltonian for a time specified by the parameter.
