20 Feb 2011 | | Abstract: | We report some improvements to the gradient ascent pulse engineering (GRAPE)
algorithm for optimal control of quantum systems. These include more accurate
gradients, convergence acceleration using the BFGS quasi-Newton algorithm as
well as faster control derivative calculation algorithms. In all test systems,
the wall clock time and the convergence rates show a considerable improvement
over the approximate gradient ascent. | | Source: | arXiv, 1102.4096 | | Services: | Forum | Review | PDF | Favorites | |
