FIG. 1.

(Color online) Flipping the Bloch vector from thermal equilibrium at into state (0,0,1) for target time . , , temperature , , and . Solid lines (black), direct PORT optimization of a steplike constant field (DO); dashed lines (red), indirect method based on PORT result (DOI); dotted lines (green), genetic-code optimization (GA); and dot-dashed lines (blue), indirect method based on GA result (GAI).

FIG. 2.

(Color online) Flipping the Bloch vector from state (1,0,0) into for target time , , , temperature , , and . The top part shows the and components and the magnitude of the Bloch vector, as indicated in the figure, whereby the intermitted lines show results for indirect optimization and the solid lines for genetic-code optimization. The bottom part of the figure shows the selected optimal control: dashed (red) line, indirect optimization; solid (black) line, genetic-code optimization.
