Self-consistent Quantum Iteratively Sparsified Hamiltonian method (SQuISH): A new algorithm for efficient Hamiltonian simulation and compression
Diana B. Chamaki, Stuart Hadfield, Katherine Klymko +2
It is crucial to reduce the resources required to run quantum algorithms and simulate physical systems on quantum computers due to coherence time limitations. With regards to Hamil…
Quantum Alternating Operator Ansatz (QAOA) Phase Diagrams and Applications for Quantum Chemistry
Vladimir Kremenetski, Tad Hogg, Stuart Hadfield +2
Determining Hamiltonian ground states and energies is a challenging task with many possible approaches on quantum computers. While variational quantum eigensolvers are popular appr…
Quantum technologies for climate change: Preliminary assessment
Casey Berger, Agustin Di Paolo, Tracey Forrest +4
Climate change presents an existential threat to human societies and the Earth's ecosystems more generally. Mitigation strategies naturally require solving a wide range of challeng…
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…
Classical symmetries and the Quantum Approximate Optimization Algorithm
Ruslan Shaydulin, Stuart Hadfield, Tad Hogg +1
We study the relationship between the Quantum Approximate Optimization Algorithm (QAOA) and the underlying symmetries of the objective function to be optimized. Our approach formal…
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…
