Dynamical Simulations of Schrödinger's Equation via Rank-Adaptive Tensor Decompositions
N. Anders Petersson, Chase Hodges-Heilmann, Stefanie Günther
We study low-rank tensor methods for the numerical solution of Schrödinger's equation with time-independent and explicitly time-dependent Hamiltonians, motivated by large-scale si…

Non-degenerate Marginal-Likelihood Calibration with Application to Quantum Characterization
Mohammad Motamed, N. Anders Petersson
We propose a marginal likelihood strategy within the Kennedy-O'Hagan (KOH) Bayesian framework, where a Gaussian process (GP) models the discrepancy between a physical system and it…

A time-parallel multiple-shooting method for large-scale quantum optimal control
N. Anders Petersson, Stefanie Günther, Seung Whan Chung
Quantum optimal control plays a crucial role in quantum computing by providing the interface between compiler and hardware. Solving the optimal control problem is particularly chal…
