1. A quantum dot array comprising:
a plurality of quantum dots including first, intermediate, and second quantum dots independently controlled by a controller to support a given type of non-Abelian anyon under respective electromagnetic field environments, with the controller configured to vary the intermediate quantum dot between its respective electromagnetic field environment and an OFF state;
wherein, in a first case configured by the controller, with the first and second quantum dots under their respective electromagnetic field environments and the intermediate quantum dot in the OFF state, a first tunneling barrier of the given type of non-Abelian anyon, between the first quantum dot and the second quantum dot, is above a first limit; and
wherein, in a second case configured by the controller, with the first and intermediate quantum dots under their respective electromagnetic field environments, a second tunneling barrier of the given type of non-Abelian anyon, between the first quantum dot and the intermediate quantum dot, is below a second threshold.
