Transform before linearizing: robust Newton methods for singular -Laplace and -Stokes equations
Gonzalo G. De Diego, Fortino Garcia, Georg Stadler +1
For , the -Laplace equation and its -Stokes generalization are difficult to solve numerically. Newton's method converges rapidly only close to the solution, with itera…
Deterministic and Bayesian Characterization of Quantum Computing Devices
Zhichao Peng, Daniel Appelö, N. Anders Petersson +3
Motivated by the noisy and fluctuating behavior of current quantum computing devices, this paper presents a data-driven characterization approach for estimating transition frequenc…
Mathematical approaches for characterization, control, calibration and validation of a quantum computing device
Zhichao Peng, Daniel Appelo, N. Anders Petersson +2
Quantum computing has received significant amounts of interest from many different research communities over the last few years. Although there are many introductory texts that foc…
Extensions and Analysis of an Iterative Solution of the Helmholtz Equation via the Wave Equation
Fortino Garcia, Daniel Appelö, Olof Runborg
In this paper we extend analysis of the WaveHoltz iteration -- a time-domain iterative method for the solution of the Helmholtz equation. We expand the previous analysis of energy…
El-WaveHoltz: A Time-Domain Iterative Solver for Time-Harmonic Elastic Waves
Daniel Appelö, Fortino Garcia, Allen Alvarez Loya +1
We consider the application of the WaveHoltz iteration to time-harmonic elastic wave equations with energy conserving boundary conditions. The original WaveHoltz iteration for acou…
Optimal Control of Closed Quantum Systems via B-Splines with Carrier Waves
N. Anders Petersson, Fortino Garcia
We consider the optimal control problem of determining electromagnetic pulses for implementing logical gates in a closed quantum system, where the Hamiltonian models the dynamics o…
