Abstract
A process for bang-anneal-bang quantum optimization includes: identifying base curve $v(t)$; setting a total runtime of the process; creating an initial guess for parameters in an ansatz; creating an initial guess for parameters in an ansatz; evolving a quantum state from a ground state of B following Hamiltonian $H(t) = u(t) B+(1-u(t)) C$ and, at termination of evolving the quantum state, measuring the resulting quantum state; updating the parameters for the ansatz based on the resulting quantum state; repetitively creating the ansatz for $u(t)$, evolving the quantum state from the ground state of $B$ following Hamiltonian $H(t)$, and, at termination of evolving the quantum state, determining the resulting quantum state until the classical outer loop converges to a selected convergence limit; and returning the final form of $u(t)$ to perform bang-anneal-bang quantum optimization.
