| contents | We solve the one-dimensional Helmholtz equation in several scenarios using the quantum annealer provided by the D-Wave systems within a pseudospectral scheme, where its solution is encoded into certain set of suitable basis functions. We assess the performance of different strategies of encoding based on algebraic arguments and the adiabatic condition, and benchmark these against the classical heuristic simulating annealing algorithm. In particular, we compute the minimum energy gap, the so-called dynamic range and the mean squared error to assess the numerical stability, consistency and accuracy of the solutions returned by each strategy. Our work stresses out the importance of developing custom embedded techniques ensuring well-conditioned algebraic systems. In particular, we find out that encoding strategies retrieving algebraic systems exhibiting full-rank and small dynamic ranges enhance the performance of the quantum annealer even under polychromatic driving and for intricate initial conditions. We further discuss the prospect of developing hybrid quantum-classical schemes enable to meet suitable algebraic and adiabatic conditions simultaneously. |
