Abstract

The invention relates to methods for characterising noise in quantum dynamical processes. The method includes estimating a Lindbladian generator for a noise quantum channel. Eigenvalues of the transfer matrix representing the noisy channel are calculated and a logarithmic branch shift list is applied to explore other branches of the logarithm. An initial guess for the Lindbladian is provided and a fitting procedure is used to improve the best guess estimate of the Lindbladian. The invention also relates to gauge optimisation to characterise State Preparation and Measurement (SPAM) errors.
