Adiabatic Quantum Simulation of Quantum Chemistry
Ryan Babbush, Peter J. Love, Alán Aspuru-Guzik
We show how to apply the quantum adiabatic algorithm directly to the quantum computation of molecular properties. We describe a procedure to map electronic structure Hamiltonians t…
Hamiltonian gadgets with reduced resource requirements
Yudong Cao, Ryan Babbush, Jacob Biamonte +1
Application of the adiabatic model of quantum computation requires efficient encoding of the solution to computational problems into the lowest eigenstate of a Hamiltonian that sup…
Resource Efficient Gadgets for Compiling Adiabatic Quantum Optimization Problems
Ryan Babbush, Bryan O'Gorman, Alán Aspuru-Guzik
We develop a resource efficient method by which the ground-state of an arbitrary k-local, optimization Hamiltonian can be encoded as the ground-state of a (k-1)-local optimization…
Force-Field Functor Theory: Classical Force-Fields which Reproduce Equilibrium Quantum Distributions
Ryan Babbush, John Parkhill, Alán Aspuru-Guzik
Feynman and Hibbs were the first to variationally determine an effective potential whose associated classical canonical ensemble approximates the exact quantum partition function.…
